I am an ecosystem ecologist broadly interested in the recovery of ecosystem functioning following habitat restoration or adoption of sustainable management practices. I work in restored tallgrass prairies and regenerative agricultural systems in Minnesota. I study the ecosystem impacts of different restoration or management practices, the recovery of soil carbon and nutrients, and how the impacts of global change influence restoration and management approaches.

Current research questions include:

• How should restoration approaches be revised to make grasslands resilient to climate change?
• Are cattle or bison grazing effective management tools for maintaining biodiversity in grasslands?
• What is the functional role of dominant grass species on ecosystem functioning in restored prairies?
• How does the modern assemblage of mammalian herbivores in prairie influence ecological processes?
• Do regenerative agricultural practices restore soil quality on degraded lands?

I am also involved in collaborative research projects with the Minnesota DNR and local Northfield farmers. These projects include investigating management strategies for invasive species in native prairies and monitoring the effects of regenerative agricultural systems on ecosystem processes.

For current highlights, follow the Carleton Ecology Lab on Twitter @Eco_Carls

I teach a range of courses at Carleton related to Ecology and Conservation, including:

• Ecosystem Ecology (BIOL 321/322)
• Global Change Biology (BIOL 210)
• Grassland Ecology (BIOL 374)
• Conservation Biology (BIOL 366)
• Food, Forests, and Resilience: Systems of Sustainability in Oaxaca, Mexico (OCS offered Winter break 2022)

I also co-teach a summer field course in ecology and conservation with the UC Santa Cruz Doris Duke Conservation Scholars Program.
