Concentration Advisor for Geochemistry and Environmental Chemistry / Earth and Planetary Science


I obtained an AB in Geology with a minor in Biology from Carleton College and a PhD in experimental rock deformation from UCLA. My research at Brown involved experimental investigations of the deformation mechanisms, microstructures, and rheology of crustal rocks, in order to interpret their thermomechanical history from preserved microstructures and to predict their mechanical behavior over a range of condition. I have greatly enjoyed collaborative undergraduate teaching of introductory courses as well as undergraduate advising, and I currently serve as a first year and sophomore advisor as well as Geoscience and Geochemistry concentration advisor.
