Research Areas

I am a paleoecologist and limnologist combining historical diatom community data with current field observations and modern ecological experimentation to understand drivers of aquatic community change. Particularly, I examine how changes in the mass balance of glaciers in arctic and alpine areas alter phytoplankton communities over the Holocene. I am also interested in inquiry-based science teaching strategies as well as STEM diversity.
