Chemistry Department Annual Report 2023 cover in Orange

Introduction

Welcome to the Chemistry Annual Report.

Wow, what a year in the Chemistry Department! We have lots of info to share with you about faculty, staff, and student accomplishments throughout the year, so please read on.

I just want to take a little space at the beginning of the 2022-23 Annual Report to share a bit about changing faces around the department. We were very pleased to have Kate Sammons and Rachel Horness join us this past year, and we are fortunate that Rachel is back for another round in 2023-24. In February, we welcomed Carrie Flesch as our new lab manager and instrument technician. Carrie hit the ground running and has been a wonderful support to the teaching and research we are doing in the department, and we are so pleased to have her on the team!

As if that weren’t enough, we have THREE new faculty members this fall: Kaz Skubi ’11 and Tamra Lahom have joined in tenure-track Assistant Professor positions, and Isaac Blythe has started as a Visiting Assistant Professor. Kaz is a synthetic organic chemist joining us most recently from teaching stints at St. Olaf College (we won’t hold that against him) and Skidmore College, and before that PhD work at University of Wisconsin and postdoctoral research at Yale. Tamra is a biochemist who just finished her PhD work at Emory University last summer and is joining us this fall before taking a break to join Squire Booker’s lab at Penn State for a postdoc before she returns full time. Isaac also received their PhD from University of Michigan last summer for work in synthetic organometallic chemistry (a field near and dear to my heart) with Melanie Sanford, and will be teaching introductory and inorganic chemistry courses this year. These new members (plus Carrie and Rachel, who joined somewhat recently) have brought a tremendous amount of energy and great new ideas in the department, and it is shaping up to be a great year!

With all of these new faces, we also will be saying goodbye to some cherished colleagues. Prof. Dave Alberg retired at the end of the 2022-23 academic year, a momentous event that was celebrated by “Dave Alberg Day” in the fall. Prof. Will Hollingsworth is also currently in his final year teaching at Carleton, and we intend to celebrate him in style as the year draws to a close. Many alumni carry such fond memories of Dave’s Orgo 1 and Will’s Quantum Chemistry courses, and we will really miss seeing them every day and working closely together, though we fully expect that they won’t be strangers.

On a sad note, we bid farewell to longtime colleague Chuck Carlin, who passed away in January of this year. I encourage you all to read the extensive entries from friends and alumni in the Carleton Farewells page. It was really a joy for me to experience secondhand some of Chuck’s impact on students and colleagues.

Amidst all this change, we are also currently searching for a tenure-track physical chemist to join our department, so I hope to have more exciting updates when we reconnect again this time next year! For now, I hope you’ll enjoy reading updates from graduating seniors, faculty, and Carleton classmates.

Diversity, Inclusion, Equity, and Respect (DIER) in Chemistry

We continue to work on making the Chemistry Department a place where everyone feels valued. We want to affirm our commitment to supporting you all whenever and however we can. We continue to explore the ways in which we can improve in developing the talents of, and empowering, scientists from backgrounds that have not traditionally been well-represented, in order to change chemistry for the better, and we count you as important partners in our efforts to identify and address these issues.

Our values statement and departmental action items can be found in our webpage. Please do not hesitate to reach out to any member of the Chemistry Department if you have any questions or want to discuss DEIR issues further.

Also, see the American Chemical Society’s statement on Diversity, Inclusion, and Respect in Chemistry.

David G. Alberg, 1993-2023, Professor Emeritus, 2023-. B.A., Carleton College; Ph.D., University of California, Berkeley.

As of August 31, 2023, I completed my 30th year as a Carleton Professor.  I celebrated the milestone anniversary by choosing to cross an even greater milestone – I’ve retired!  My decision to retire is not due any dissatisfaction with the job – I can’t imagine a better gig!  I know I will sorely miss working with the curious and enthusiastic Carleton students (admittedly, there are a few things I won’t miss, like grading exams!).  Thirty years just felt like the right time.  Our two kids, Sam and Ellie, are fully launched and we’ve even welcomed a wonderful daughter-in-law to our family with Sam’s recent marriage to Katherine Snell.  I still enjoy good health and, happily, I remain able and willing to run in the Arb every other day – often with Steve Drew pushing me to run a bit faster than I might like.  The Arb is a favorite place of mine and spending time there helps maintain both my physical and mental health.  I am also fortunate to have many good friends whom I see regularly, and other friends with whom I would like to reconnect.  Retirement offers precious time to savor this very good life!

Of course, people ask me what I’m going to do in my retirement.  At this point, I’m not entirely sure, so I’m taking a gap year to figure that out.  My wife, Gretchen, is returning to the department after 7 years working in the Dean’s office, so I’ll keep things running at home while she shakes off the rust and returns to the classroom.  I admit that retirement is feeling pretty good right now as I watch Gretchen anxiously preparing to teach in less than two weeks.  I get to escape that melancholy and apprehensive feeling that has been a staple in my life as summer slides into fall.  Once the term starts there is no getting off the rollercoaster until the end of final exams.  Rather than hopping on the rollercoaster, I am easing into retirement by returning to the research lab.  Gretchen and I are working to bring to fruition our longtime collaborative research project in organocatalysis.  It’s been fun working in the lab on my own time – frequently having the NMR to myself!  The research also keeps me engaged with my longtime love of chemistry.

As I look back on my career it is readily apparent that what has made this job so special are all the marvelous students and superb colleagues I have had the great good fortune of working with.  Thank you all!

Christopher Calderone, 2012 – Associate Professor. B.S., University of Chicago; M.Phil., Cambridge University; Ph.D., Harvard University.

Though I just finished my tenth year at Carleton, there’s still new things to learn and courses to teach….In addition to my usual offering of CHEM123, I also taught Kinetics (with Trish Ferrett) and BIOC331 Current Topics in Biochemistry, each for the first time.  I particularly enjoyed teaching Kinetics—it’s so rare that we have an opportunity to team-teach a course with someone else in the department, and it was a treat to be able to do so this Fall with Trish.  It was also nice to finally get to teach Kinetics for the first time—I’ve heard so much about the course from both faculty and students as a rite of passage in the major, and I finally see why it is such an important and unifying course in the curriculum.  I’m not on the schedule to teach it next year, but hopefully I’ll get another chance in the near future.

It was also a blast to teach BIOC331 for the first time—in fact, the first time the course was ever offered!  It’s a seminar-style course that’s meant to be a capstone for biochemistry minors, and it was gratifying that there was sufficient demand for the course that we had to add a second section at the last minute.  I got to read a lot of really interesting papers with some really smart students, and I’m looking forward to teaching it again next year.

I’m going to be spending Fall and Winter terms next year working at the University of Minnesota, in Ambika Bhagi-Damodaran’s lab tying up some loose ends on some of the projects I’ve been working on at Carleton and getting started on some new ones.  It will be nice to come back to my Carleton lab recharged and with some new ideas to explore.

Charles H. Carlin, 1966-2004; Charles “Jim” and Marjorie Kade Professor of the Sciences, Emeritus, 2004-2023. B.A., Carthage College; Ph.D., The Johns Hopkins University.

Chuck passed away January 2, 2023 at the age of 83. Please check out his Farewells page for tributes and memories from students, colleagues, and friends.

Marion E. Cass, 1987-2019; Professor Emeritus, 2019-. B.S. Fort Lewis College, Durango Colorado, Ph.D., University of Colorado at Boulder.

It’s been an interesting year!  In the opening of the 22-23 academic year (Aug/Sept 22) I was wrapping up my second trip to the villages of Qaanaaq, Siorapaluk and Qeqertat Greenland. 

Steve and I worked with Mary Albert (Thayer Engineering School at Dartmouth) and a group of her graduate students on an NSF Grant funded by a Program, “Navigating the New Arctic”, to address some of the issues that northern areas will face as a function of climate change.  The villages we visited are populated by native hunters/fishers of the Inughuit people and our mission is to reduce their dependency on imported diesel as an energy source.  Steve and I worked with one graduate student carrying out energy audits and evaluations on the energy efficiency of their buildings.  Steve and one graduate student also examined the power generation plants in the towns. Our August trip was a bit different than what we planned.  It began with a relatively scary attempted yet aborted landing at the Thule Airforce Base (in 60 mph cross winds).  Our plane was diverted to Iqualit, Canada where we spent 5 days exploring the town and Frobisher Bay constantly poised to be called up to reboard our military transport plane.  We did make it to Qaanaaq, then Siorapaluk, and back to Qaanaag.  Unexpectedly I came down with Covid-19 and was quarantined for 10 days unable to travel.  The entire team needed to head home without me.  Because there are only weekly flights back to Thule Airforce base and back to the US, I ended up having two amazing experiences. The first involved witnessing a Beluga whale hunt from the hillside just out of town.  An unfortunate small pod of Belugas ventured too close to the town. To the delight of everyone but me and the Belugas (towns people, sled dogs, school kids) 9 Belugas were hunted down and brought in to replenish the meat supply.  My second amazing experience occurred when no longer under quarantine but before my helicopter flight out, our hosts took me on a boat ride up the fjord from Qaanaaq to Qeqertat, a very remote village with only a handful of residents (25?).  The trip weaving through icebergs as large as battleships and as small as basketballs will stay with me throughout my lifetime.  Ultimately, did our work make a difference? Will buildings be upgraded?  Will generators be run in different algorism?  Will some sort of solar be installed to supplement diesel in the summer (of 24 hour sun)? We don’t know but we have hopes that our work has identified some ways that can help. The work continues.

Other projects Steve and I participated in this year are the following.  We were able to consult with a set of property owners who purchased a property within the wilderness boundaries of Idaho near the Salmon River on their options and potential for solar energy.  We visited several cannabis growing facilities in Massachusetts and Maryland to measure the energy consumption of their heating, cooling and lighting, again with the aspiration to lower their energy consumption.  We visited (on invitation) a mansion in Connecticut (that uses $35K of electricity and $35K of propane per year) to help identify energy efficiency opportunities, and we installed Lithium Ion Phosphate batteries and upgraded two solar arrays to an off grid property in rural Maine. Last not but not least, In December we traveled to meet 4 Dartmouth student and a group of employees from the Irving Oil company in the Netherlands to visit a National Lab and several facilities that are installing green hydrogen for heating. The trip was illuminating and inspirational.

At home in Lyme we hang out with our dogs Ada (soon to be 15!) and Jenny.  We cook, ski when there is snow, swim when it is warm and enjoy the quiet solitude.  Best wishes to you all!  I miss Carleton and all of you greatly and think of you often!

Joseph W. Chihade, 2003-, Professor. B.A., Oberlin College; M.A., Ph.D., Columbia University.

It’s been quite an eventful year for me, full of changes, new challenges, and some adventures. One of the more familiar pieces was my teaching; I taught Chem 233 in both the Fall and the Winter terms and was able to try out some of the group-based problems that I had developed for remote teaching in an in-person setting, teaching in the “sandbox” room in Weitz. I always enjoy teaching Orgo I, since it is such a new way of thinking for most of the students in the course. In the Winter, I also led a comps group who delved into the work of Shana Kelley, a bio-analytical chemist now at Northwestern University. Professor Kelley’s work is wide ranging, so the group learned about everything from cancer metastasis to electrochemistry to electronic chip fabrication. They rose to this challenge very nicely, putting together all of the pieces with aplomb. One of the things I like most about our comps process is the way that it encourages the comps visitor to thoughtfully reflect on the twists and turns of their career with comps students. The pearls of wisdom that came out of those discussions this year were even more valuable than the scientific revelations. 

This year I also became the mentor for Carleton’s Class of 2026 Posse, the ninth Carleton Posse from Houston. Working with these twelve remarkable first-year students, who I met with individually and as group at least every two weeks throughout the academic year, was one of the most intense and wonderful things I have done since being at Carleton. I learned a tremendous amount about so many things, ranging from the location of good vegan restaurants in Houston to how difficult it is for first-year students to manage the vagaries of placement exams and language requirements to how Karl-Pop, the Carleton K-pop dance group, plans their shows and so much in between. I’m really looking forward to watching the Posse continue to grow, both as individuals and as a group, over the next three years. 

My research group continued to make slow but steady progress on several fronts. Lora Randa and Eledon Beyene were joined by Meredith Klay in trying to express and understand the different pathogenic phenotypes caused by mutations in the human mitochondrial alanyl-tRNA synthetase. Noah Mueller and Sara Abraha took on the challenge of following up the work that David Wilson and Molly Kamman had started last year, an effort to express in bacteria several aminoacyl-tRNA synthetases from parasitic worms, or helminths. Making these enzymes is a first step in developing inhibitors, which could be used at anti-parasitic drugs. Lora, Eledon, and Noah all traveled to Seattle in March to present their work at the ASBMB national meeting. This June, I attended the 13th International Symposium on Aminoacyl-tRNA Synthetases in Ontario and gave a talk about the helminth project. 

At home, things are relatively quiet, now that both kids are in college. Margo finished her second year at Haverford, while Sofia was in her first year at Skidmore. Both are taking a lot of chemistry classes. In fact, during their semesters, both were taking organic. Several of my old exams have thus made it to the East Coast, where they hopefully provided some useful practice for my daughters and their friends. With the kids no longer in the K-12 system, we got in some pretty exciting trips during Winter break. Dani and I were in Qatar for the end of the World Cup group stage and the beginning of the round of 16. We saw five games in five days at five different stadiums and still managed to connect with a distant cousin, visit amazing museums, and kayak in the Arabian Gulf. A short visit to Dubai the next week was also amazing. When we came back to North America, we managed to squeeze in a ski trip to Alberta before the beginning of Winter term, hitting the trifecta or Mt. Norquay, Sunshine, and Lake Louise despite Delta misplacing our skis for several days. Not sure that the coming year will be quite as full, but watch this space to find out.

Nancy and I continue to enjoy performances by the Minnesota Orchestra, the St. Paul Chamber Orchestra, and the Minnesota Opera.  We venture beyond the Twin Cities to state parks and favorite haunts along the north shore of Lake Superior, although the extreme heat of last summer limited this activity.  Life remains pleasant among our friends at Village on the Cannon, where we recently marked our seventeenth year as residents.  I still find subjects for photography in easily accessible places and enjoy the challenges of editing them.

I was back to teaching full time this past year.  I had the opportunity to teach Principles of Chemistry II, Instrumental Chemical Analysis, and a revival of my course on computer interfacing and electronics which I have now titled Computer-Assisted Experimentation for Chemists.  This was a very fun selection of courses to teach with a lot of great analytical chemistry content.  As usual, working with the new flocks of Carleton students is a joy and a challenge – plenty of enthusiasm and engagement with a lot of difficult, probing questions that nudge me to think of new ways to explain chemical phenomena and instrumentation.  A couple of highlights from teaching this year included expanding our instrumentation fleet in Instrumental Chemical Analysis to include a new microwave plasma atomic emission spectrometer (Deborah provided the leadership to make this happen).  I developed a new experiment students performed with the MP-AES in conjunction with measurements on our flame AAS instrument.  I also had a student group take on a project for Loon Liquors here in Northfield to measure phenols in smoked barley using HPLC with UV absorbance detection.  This went pretty well, considering it was our first attempt, and the student group had useful data to share.

During the academic year Gavin Hazen, Ethan Li, and Sean Zhang continued to do research in my lab along with three other students who opted to do research for their chemistry comps.  We are currently working on developing electrochemical deposition methods for making thin films of an iron-chromium-aluminum mixed metal oxide semiconductor that have potential in photoelectrochemical water splitting.  Gavin and Ethan have now been working with me for two years and returned to the ACS meeting this past spring to present another poster on their work, this time detailing their foray into electrochemical deposition.  They are both off to the University of Illinois this fall.  I will miss them.  However, I already have new student interest to work in my research lab and I look forward to getting to know a crop of new students in the coming year.

Tricia A. Ferrett, 1990-, Professor. B.A., Grinnell College; Ph.D., University of California, Berkeley.

This past year I taught with zeal (!) the usual range of upper-level physical chemistry courses plus Comps. Fall term, I taught Chem 301 (Chemical Kinetics Lab) with Chris Calderone – my first time teaching with Chris and after a number of years away from this research methods course.  We followed the able lead of a number of our colleagues who have continued to revise this course. I had fun with a finnicky fast fluorescence spectroscopy lab (lots of troubleshooting) along with a number of term-long kinetics projects (more troubleshooting, as usual). Students were highly engaged with their projects – some old, some new. The cool nanochemistry synthesis/kinetics project drove us crazy but was conquered. We also taught and used some kinetics software to model and understand more complex kinetic systems – a great addition to this course.

Winter term was fun and stimulating but extremely busy. I taught Chem 344 (Quantum Chemistry) and Chem 302 (Quantum Spectroscopy Lab) plus a comps group of 9 seniors.  These two quantum courses are no longer required but exist on a menu of options for our majors. I had fairly large classes animated with my usual “classical” quantum toys (slinky, spinning top, and the Astrojax spinner). I continued from my pandemic practice of having students do much individual work  in plus work in teams of 2-3 on weekly challenge problems and several group quizzes. I gave rich feedback on all team assignments.  I also made major revisions to the Chem 302 lab now that it is taught by just one faculty member. I introduced and hope to expand a new lab on quantum dots and conjugated dyes.

In winter and spring terms, I was privileged to work with 9 seniors in a comps group on the work of Teri Odom (Northwestern University, Chemistry) studying the synthesis and applications of surface-functionalized gold nanostars.  The comps group became independent early on – creating discussion questions and responses in a Google doc prior to each meeting and leading fruitful discussions.  A number of difficult literature papers were “demolished” (as they said) with curiosity, team work, agile process tuning, and persistence! The group talk in April told a wonderful story of using gold nanostars for targeted cancer treatment. Our April visit with Teri Odom was inspiring, rich, and busy with 5 hours of conversation, flowers, pastries, Thai food, and both human and scientific stories.  This was the largest comps group of my career, and the seniors rose to all challenges!

Spring term I was not teaching, but I spent four months of full-time effort to move my 92-year old mother from Colorado to Minnesota (including 2 medical events and 7 transitions). I am now managing all her affairs and spending several hours with her daily at a local nursing home.  I am grateful Mom is close, but this has been a sea change in my daily life. Most travel this past year was to Colorado (every several months) to visit Mom and my 2 brothers. Gerard and I had a wonderful week in a cabin in December near Ely MN, where we nested, snowshoed, and played with sled dogs. Retirement is 1-2 years away. I continue to enjoy my many gardens, getting outdoors, exercise (run, bike, walk, yoga), cooking… and in the winter several fiber arts and following Alaskan dog sledders. Partner Gerard keeps biking like a madman; he talked me into getting an e-bike this spring which I love!  He has transformed much of our yard to a stunningly beautiful wildflower meadow. I look forward to several more years of teaching and then an active retirement, mostly outdoors.

I began my Carleton journey on February 20th, 2023.  I was able to hit the ground running because of the guidance I received from Julie Karg.  My spring term was spent getting acquainted with lab set ups and some instrumentation/equipment.  

I want to give many thanks to the department, colleagues and students who are helping me get accustomed to my new position.  I really appreciate it.

This has been a busy year, filled with department hiring, co-leading an off-campus program, research, comps, directing the FOCUS Program, independent studies, classes, etc. It has been exciting and a bit overwhelming to watch our department population change quickly! This year, Dave Alberg’s retirement, which is richly deserved, makes it seem like I’ve been here forever – Dave earned tenure my first year at Carleton! The passing of Chuck Carlin, whose kindness leaves ripple effects that are still evident in the chemistry department, was sad news for all of us. I have the great honor of having completed the first year of my five-year term as the Charles “Jim” and Marjorie Kade Professor of the Sciences, a position held by Chuck (and then by Marion Cass and Steve Drew), an inspiring lineage! Hiring new tenure-track and visiting faculty, as well as new staff, keeps the department vibrant and exciting to be a part of.

Last summer, I had the pleasure of working with four research students (Nora Caballero ’23, Margaret Hall ’25, Audrey Parrott ’25, and Alek Rabago ’23). They were a great group to work with and very productive, both in analysis of cookstove data from Ethiopia and in working on developing a pellet-fueled stove to bake injera, the traditional Ethiopian bread. In the fall, I co-taught the first part of my winter break off-campus studies (OCS) course, ENTS 289, Climate Change and Human Health with Tsegaye Nega (Associate Professor of ENTS). We worked with 12 students to understand the complexities and connections between these two large, intertwined topics (climate and health), and also to prepare them for carrying out research projects related to the case study of clean cooking in Ethiopia – a topic that intersects both of these areas and has global implications. During the December break, we traveled with the students for 2 weeks in Ethiopia, where they made fantastic progress on their projects, while also gaining a deeper understanding of the human context in which these issues play out. In the winter, we all worked together in CHEM 289, Climate and Health, from Science to Practice, to understand and interpret the results of their projects and to put them together into a symposium and report. The students were a delight to work and travel with, and their passion, commitment, and enthusiasm gives me hope. We will offer this program again in 2024-2025.

In the winter, I taught the class for CHEM 224, Principles of Chemistry II for which Rachel Horness (visiting Assistant Professor) taught the lab. The 34 students were eager to learn chemistry and enthusiastic, even though we met 1a (8:30am) throughout the winter in a windowless classroom! In the spring, I taught CHEM 224 (the whole thing, class and lab). The 47 students were engaged, asked good questions, and had fun both in class and in the lab.

In addition to these courses, I worked with the sophomore FOCUS cohort, teaching their FOCUS Sophomore Colloquium. They designed and carried out projects related to sustainability at Carleton. This gave us the opportunity to work closely with Erica Zweifel from the Center for Community and Civic Engagement at Carleton (CCCE), Sarah Fortner, Carleton’s new Director of Sustainability, and Risi Karim, Assistant to the City Administrator for Northfield, MN, as well as many others around campus. The students engaged with topics from reducing single-use plastic bag use on campus to development of a textbook library to better publicizing grants available to homeowners in Northfield for energy efficient upgrades to homes (and more!). Their work will be described in the FOCUS Journal of Science, found on the FOCUS webpage. I also had the opportunity to work with a small group of FOCUS students, ably assisted by Yelena Hallman, the FOCUS 5th Year Intern, in an independent study to develop hands-on science activities to include in the STEM Night activities organized by Rika Anderson (Associate Professor of Biology). The students did a great job and the kids were excited to learn about genetics by building monster puppets and about optimization in computer code by directing either a marble or another kid through mazes!

Dani Kohen and I worked with a comps group this year who studied the work of Professor Joseph Francisco from the University of Pennsylvania. He works on atmospheric chemistry using computational techniques, so we were the obvious pair to co-lead the group! The eight seniors (Sean Boyce, Nora Caballero, William Chang-Stucki, Ania Huang, Nell Schafer, Lucy Shapiro, Will Stepanski, and Emma Watson) were enthusiastic learners and had a really fantastic visit with Dr. Francisco in May. His visit was sponsored by the Jean and Jerry Mohrig fund, and it was great to have Jerry Mohrig at the seminar!

I am writing this report at the very beginning of a well-earned (if I do say so, myself) sabbatical for the 2023-2024 academic year. Stay tuned for a report in next-year’s edition of the Chemistry Department annual report for information about what I am up to!

Gretchen E. Hofmeister, 2002-, Professor. B.A., Carleton College; Ph.D., University of California, Berkeley.

I am returning to the department and to teaching in the fall after seven years away—five as Associate Dean, one as Dean of the College, and one on sabbatical. While I relished many aspects of my roles in administration, I have really missed working with students and doing chemistry. I have spent my sabbatical preparing for my transition from administration back to being a regular faculty member. In the fall, I re-immersed myself in the research project that has been a collaboration with Dave Alberg and Dani Kohen for about ten years. Winter term, Dave and I traveled to Los Angeles and worked in the computational research group led by Ken Houk at UCLA, where we learned additional strategies for theoretically analyzing organocatalytic reactions. I also spent three weeks at UC Santa Barbara in Bruce Lipshutz’s group, learning how to use surfactants to perform transition metal-catalyzed reactions in water. Dave and I returned to Northfield in the spring and I set up my research space, where I have been running reactions for research and for a new lab project for Organic I, as well as doing lots of
NMR experiments. After a three-week summer vacation, which culminated in the marriage of our son, Sam (yay!), I am bringing some projects to interim conclusions before the term starts in September.

My research collaboration with Dave and Dani concerns the study of enantioselective organocatalysis reactions using stable transition state analogs (TSAs). Enantioselective synthesis plays a critical role in organic chemistry, most particularly in the pharmaceutical industry because most drugs are chiral. TSAs have long been used in enzymatic chemistry as potential inhibitors and therefore drug candidates for particular enzyme targets. In our case, we are studying how each enantiomer of a chiral TSA, which models the transition state, interacts with a chiral organocatalyst. The goal is to elucidate the interactions that are responsible for enantioselectivity, and use that information to identify or design better catalysts. We are using solution NMR techniques, including binding constant titrations and diffusion-ordered spectroscopy (DOSY), as well as solid state analysis by X-ray crystallography, to characterize the diastereomeric interactions that lead to enantioselectivity. We are bolstering this work with computational analysis of both the transition states and the catalyst-TSA complexes.

DOSY NMR provides diffusion coefficients, D, or indicators of molecular size, for species in solution. In the presence of a chiral catalyst, the TSA enantiomer that binds more tightly to the catalyst should appear larger and have a smaller D value than the other TSA enantiomer. If the TSA is a good model for the reaction, it should also correspond to the configuration of the major product. Until now, we have struggled to obtain reproducible D values, most likely because of convection currents. After trying several approaches, we have had a breakthrough this year that I believe has addressed the errors due to convection. I am hoping to complete the determination of new, accurate D values for our TSA enantiomers using DOSY NMR before the end of the summer. Having more robust data will enable us to evaluate with greater confidence the efficacy of our TSAs in mimicking these reactions. We will then use those results to identify the interactions that are most important in enantioselectivity.

My second sabbatical project has been to replace the Grignard experiment in our organic I teaching lab with a project that is more modern and environmentally benign. In particular, I have been drawn to Bruce Lipshutz’s work using micelles in water solution as mini “reaction flasks” for performing organometallic reactions. You may have seen the July 17 C&En News article, “Can Organic Chemists Cut Waste by Switching to Water?” which prominently features his chemistry. While working in his laboratories, I learned how they identify surfactant-metal-ligand combinations to best accomplish particular transformations, as well as how to synthesize some of the surfactants. I am currently planning to replace the Grignard reaction with a stereospecific synthesis of E- or Z- anethole (E-anethole is the major component in anise oil), using a Suzuki reaction in either an aqueous THF solution or an aqueous surfactant solution. The students would analyze the environmental impact of each approach, to evaluate which is more benign.

Finally, I have been studying the science of emotions as a way to build my skills in supporting student mental health. Faculty colleagues have shared that there has been a dramatic increase in student mental health issues and requests for accommodations since I last taught in 2016. During my sabbatical, I read Permission to Feel by Marc Bracket, who is the director of the Yale Center for Emotional Intelligence. I also completed a Coursera course offered through the center, titled, Managing Emotions in Times of Uncertainty or Stress, which is targeted towards K-12 educators. This course introduces a “mood meter” and vocabulary for identifying and processing emotions, and teaches instructors how to discuss emotions with students and have productive interactions with students when they are experiencing strong emotions. Some of the lessons from the book and course are that all emotions are legitimate and that pathologizing emotions is not helpful; rather, we need to learn how to work with our emotions. Although the course is not targeted to college teaching, I believe that it will be helpful to me in expanding my “coaching skills” for students. In other words, I am striving to adopt a “teacher as coach” model for teaching and mentoring students. In my administrative roles, I learned about the mental health support that athletic coaches routinely provide their students; my goal is to learn from them, other adopters of this form of teaching, and the course that I completed, how to incorporate appropriate emotional support for students in my courses.

Like many others, I have experienced a lot of change in the past year; I feel fortunate to have had a sabbatical leave to adjust to these changes. In addition, I am grateful to have been able to return to activities that I enjoyed pre-COVID, such as swimming three times a week with my Masters Swimming Group, the Knightcrawlers. Altogether, my sabbatical activities give me confidence that I am ready to return to the classroom!

William E. Hollingsworth, 1986-, Professor. B.S., B.A., University of Texas, Austin; M.S., Ph.D., University of California, Berkeley.

This was my first of two years phasing to retirement, so I am pretty much teaching each class for the last time. It’s been quite a run, but it is bittersweet to know this time will be the last time teaching each of these classes. This year I taught Chem 343 (Chemical Thermodynamics) in the winter and Chem 128 (Principles of Environmental Chemistry). Teaching thermodynamics was made all the more challenging this time due to a painfully slow recovery from Covid caught while on vacation in Alaska in early August.

Now that I am phasing towards retirement, I am not teaching every term. That allowed Tracy and me to be away the entire winter term to avoid the Minnesota winters, which seem to be getting more unpleasant with climate change. We took two extended trips, the first to Australia and New Zealand, and the second to Arizona and California. Highlights of Australia included visiting the island state of Tasmania and seeing wallabies and pademelons in the woods, smaller marsupials that have not been decimated by invasive predators. In New Zealand, it was seeing the southern mountains and taking a boat ride of spectacular Milford Sound.

Rachel Horness, 2022-, Visiting Assistant Professor. B.A., Kalamazoo College; Ph.D., Indiana University.

The 2022-2023 academic year was one full of exciting and challenging changes. I moved to Minnesota permanently late in the summer of 2022. In a time where moving my life meant a lot of new things, it was surreal to walk around Carleton’s campus where so much felt reminiscent of my own college experience. I shared in the nervous excitement of the first-years for the coming year. In the fall term I was lucky to be able to teach Chem 123. With a mix of first-years sharing my own feelings about adjusting to a new place and experienced students willing to show us the ropes, I’m not sure I could have been in better hands. Our office hours were full of laughs, our labs were lively, and I was able to learn so much.

The winter term hit hard. I had a tremendous sense of foreboding as I sat, completely and utterly stuck in a snow bank on the first day of classes. Luckily, things started looking up from there. I got to teach some of my favorite concepts in Biochemistry 301. It was a big change transitioning from my previous biochemistry classes of 150 students to a class of 16, but everyone was patient as I worked to adjust. At the same time, I was teaching the lab portion of Chem 224. Deborah and Steve were tremendously supportive in making sure we had everything we needed in lab from solutions and equipment to words of wisdom and experience. By the time spring term arrived, I was feeling excited to return to the relative familiarity of Chem 123 and take on a new role as academic advisor to a handful of chemistry majors. We finished the term strong with a tremendously lively class providing all the energy we needed to make it to the end of the year, sunny days, and warmer weather.

Though life at Carleton is plenty busy on its own, I also spent some time exploring my new home. Outside of school I wandered in parks, looking for new favorite trails. Being a new homeowner meant lots of house projects (like completely renovating our guest bathroom days before having our first guests), painting, re-painting, and settling in. And, as always, I spent plenty of time breaking in my new kitchen with baking projects galore.

Julie Karg, 1988-, Chemistry Technician. B.S., Mankato State University.

Academic year 2022-2023 brought 2 new temporary faculty (Kate Sammons and Rachel Horness) and a new Laboratory Manager and Instrument Technician (Carrie Flesch) to the department and saw the departure of a 30-year tenured faculty member (Dave Alberg).  I have had the opportunity to work with all of these individuals, especially Dave.  I’ve prepared the Organic Chemistry I laboratory course for as long as Dave’s been teaching it.  I’m not sure how long that’s been, but it was odd preparing it for someone else winter term.  In the fall, the department will be welcoming new temporary and tenure-track faculty that I will have the opportunity to work with.

Daniela Kohen, 2002-, Professor. B.A., Universidad de Buenos Aires, Argentina; Ph.D., University of Notre Dame.

Last year, I transitioned from my role as the chair of the department to just being a chemistry professor. It was quite great! While serving as chair, I had my share of highlights and accomplishments that I am proud of. However, I truly cherished the opportunity to dedicate more time to research!

This was especially crucial as my research group is now part of a collaborative project funded by the DOE, involving four groups from other institutions. This initiative demanded a significant portion of my attention to get off to a successful start. This new endeavor focuses on studying porous materials like zeolites and metal-organic frameworks. These are materials I have been working on since the beginning of my independent research career, but in this collaborative project, our team’s goal is to enhance, develop, and expand computational and theoretical chemistry methods, along with data-driven scientific approaches, for applications in adsorption cooling and separations. Collaborating with other groups at R1 universities has proven to be highly rewarding, granting my students (and myself) the opportunity to engage in research that would have otherwise been inaccessible.

Conducting research during the summer was also truly a pleasure. Aside from Henry Wolters (’26) and Nathan Wang (’26), who are part of the DOE-funded team, Katherine Geist (’24) continued our work on cation motion in zeolites. In all of our studies involving porous materials, computer simulations remain invaluable for gaining microscopic insights into intriguing behaviors. Furthermore, Claire Lee-Zacheis (’26) and Aidan Khan (’25) continued our previous research into mechanisms and reactivity within the systems studied by the Whited group. Whenever I visited my students in our beautiful research space in Hulings, it was inspiring to witness their enthusiasm for conducting research in each other’s company! I so relish the chance to guide and support our students and share with them the highs and lows of research!

Naturally, I also continued to teach. I offered courses in introductory chemistry, computational chemistry, and comps, as I have done on numerous occasions throughout my career. Introducing Carleton students to the “wonders of chemistry” never ceases to be fulfilling. Teaching these courses allows me to see how our students evolve and mature during their time at Carleton, apart from the acquisition of chemistry knowledge, of course! Additionally, in response to student interest and our department’s commitment to promoting Diversity, Equity, Inclusion, and Respect, I designed a new three-credit course, CHEM 371: Chemistry and Society – Impact and Legacy. In this course, small groups of upper-level students developed case studies for use in introductory chemistry courses. These case studies explore the impact and legacy of social issues in chemistry. Additionally, the students prepared posters that are now proudly displayed on our walls. I hope to offer this course every other year, ensuring a consistent opportunity for students.

On the personal front, Joe and I have officially finished our first year as “empty nesters.” Margo is at Haverford and Sofia is at Skidmore, and both are thriving. It’s pretty great to witness their growth while enjoying this new phase of our family life!

The steady supply of cookies for the Chemistry Seminars picked up to a more normal level than it had been for the past few years. It is nice to have something feel a bit more normal.

I still compile content for The Weekly Beaker and for this Annual Report, I manage the department’s website while continuing to learn more about WordPress and now Workday, along with my usual office duties. As I look back on my 7 years with Chemistry and Geology, I tell others that I am waiting for a year with no major changes. Might this happen in this next academic year?

There is not much to say this year, except for the fact that I am still getting around on my walker. It’s hard to believe that it has been six and a half years since the stroke that took away my balance. I get over to Carleton now and again to seminars and meetings with students, often by getting rides.

I am the convenor of the Community Conversations group at Millstream Commons and chair the Resident Council here at Millstream. I have been able to travel to Massachusetts twice to see my wife Adrienne, who is there with her daughter, once with my son David and once with my daughter Sara. I am unable to travel alone. We now travel first class which is far less tiring than economy class. Usually, I am invited to reunion dinners and meet regularly with friends, including the Men’s Group of the United Church of Christ.

I wrote my last annual report contribution from North Carolina, halfway through a wonderful sabbatical doing research at UNC. So much changes in a year! I had a great time working on some nickel chemistry and doing some electrochemistry, but I never completely separated from Carleton since I co-led our tenure-track search last fall and was planning to come back as STEM Director in December. Being Department Chair and STEM Director has definitely made my calendar more crowded, but the positions have also given great opportunities to meet new people and support department and cross-department work at Carleton in new and creative ways. I have also been deeply involved with several teams working on strategic planning, including the Financial Aid Working Group and Advancing the Liberal Arts task force. Stay tuned for exciting progress from strategic planning soon. All in all, I’m enjoying the new challenges!

I spent some of my time last summer finishing a new NSF grant application, which was funded (yay!) just a few months ago. Those funds will support research with approximately 18 Carleton students over the next 3 years. Six students joined my lab on this project, which involves devising new strategies for engaging abundant and non-toxic metals in catalysis: Collin Pearson, Annika Stewart, Marshall Johnson, Quan Nguyen, Claire Lee-Zacheis, and Aidan Khan (Claire and Aidan were co-advised by Dani Kohen and worked on computations). It was my first time in a while having 100% turnover with a group of summer students, but I ended up being so impressed by their work! We have made fantastic progress on a couple of fronts, and I am optimistic that we’ll be putting papers together on their work next summer.

After returning from sabbatical, I led a comps group studying Prof Shannon Stahl’s (U Wisconsin) work on catalytic electrochemical oxidations using organic mediators. That group was super fun, and the students put together a fantastic presentation and (as usual) impressed our visitor when he came to campus. In the spring, I was back to teaching inorganic chemistry and lab after a year off. No rest for the weary, but all good things for sure. I am excited that Isaac will be teaching inorganic chemistry this year and will be working closely with them to think about new lab ideas (and if I’m lucky, maybe even having Isaac contribute to some ongoing projects in my research lab).

At home, my boys (who were not born when we moved to Northfield) are now 10 (Andrew) and 12
(James). Having a middle schooler is moderately terrifying to me, but the kids are also so much fun at this age that I’m willing to set aside my personal discomfort with aging. Charlotte has been kept busy in the Grants Office, with a third straight record year for faculty grants! I’m happy to say that I contributed (modestly) to the total this time around. We love Carleton and Northfield, which is good because with all this hiring we are quickly transitioning from newbies to long-timers.

Crochet a Flask for Chemistry!

crochet a flask

In fall 2020, Professor Deborah Gross and Katherine Mateos (’21) spearheaded a crochet-a-flask project for all chemists! Although it began as a pandemic bonding project for the department, we hope to continue having students, staff, faculty, and alums crochet Erlenmeyer flasks to display in the Chemistry Common Room in our new building. Kits of yarn, hook, thread, needle, stuffing, a pattern, and crochet tutorials were provided for socially distanced crocheting. We would love to have more contributions, so if you are (or want to be) skilled with yarn, please make a flask and send it to the department! We will add it to the display and acknowledge your contribution. Any other chemistry-themed yarn projects would be welcomed, as well!

Click here for a link to the erlenmeyer flask pattern. Contact Deborah Gross (dgross@carleton.edu) if you have any questions.
