Introduction
It was a year of change and a year of planning for change. We look ahead with trepidation, but also great enthusiasm. As you may know, we are planning for a new integrated science facility and we are just wrapping up the “design development” stage. Simultaneously, we are designing temporary transition space for our teaching and research labs because Mudd Hall will have to come down before the new construction begins. Suffice it to say that we sat through many, many meetings this year. The prospect of a new and exciting facility accounts for our great enthusiasm, while the move into temporary space explains our trepidation.
That said, the change that induces most of our trepidation this year is the very recent (June 15) retirement of our longest serving department member, Wendy Zimmerman. After 46 years of impeccable and dedicated service to a grateful department, Wendy announced her retirement in early May. We are so indebted to Wendy for her ability to corral a highly distractible faculty and to keep the department running at top efficiency. The chemistry department has an excellent reputation at the college for always meeting its obligations and carrying out its business in a timely and proficient manner, and Wendy can take the credit for this success. While the news is melancholy, we are happy for Wendy and we wish her the very best.
Although not serving the college quite as long as Wendy, we also said goodbye to a new friend, Visiting Assistant Professor Ryan Steed. After completing his second year in the department, Ryan is moving on to a tenure track position at the University of North Carolina, Asheville. Ryan was a great addition to the department, teaching both at the introductory and advanced levels (Kinetics lab, Biological Chemistry, and Biophysical Chemistry). He also co-led a comps group with Trish Ferrett this year and was able to get a jump start on his research program, working with two students last summer and through the academic year. He is more than ready to begin his tenure track appointment and we wish him, his wife Dawn, and their three children, Sam, Bennett, and Emma, the best of luck as they begin their new life in North Carolina.
Not all the changes this year were losses! We were delighted to welcome Visiting Assistant Professor Buck Taylor, who taught CHEM 123 this year, as well as Organic Chemistry II. Buck earned his BA from Willamette University and moved on to UC Irvine for his graduate work, where he developed nickel-catalyzed cross coupling reactions. After exploring transition metal-catalyzed reactions in the lab, he decided to study them computationally as an NIH Postdoctoral Fellow at UCLA. This summer, Buck is working with three Carleton students to study palladium- and rhodium-catalyzed reaction mechanisms using computational methods. We are fortunate that Buck will be with us for another year.
Tami Little is another new addition. Tami just joined the department as our new administrative assistant on July 1. Actually, Tami will be serving as the administrative assistant for both Chemistry and Geology. We were very fortunate to be able to hire Tami. She is a well-respected veteran at the college and knows how the place operates. She previously served as Administrative Assistant in American Studies, Environmental Studies, Linguistics, and Women’s & Gender Studies. After wearing so many hats simultaneously, working with just geology and chemistry should not be a problem for Tami!
We are going to miss our now graduated senior class but we look forward to following their career trajectories in the years ahead. We also look forward to seeing them and you at future Carleton reunions, ACS meetings, and other events. Finally, keep in mind that Mudd Hall will soon be gone; hurry back to campus if you want to walk its halls one last time! Keep in touch.
