I am a geologist, and my research focuses on glacial geology, Quaternary history, and climate change. Students have worked with me as research assistants in Iceland and Maine, and also in my laboratory here in the Environmental Studies Department in Gettysburg. I teach classes such as Earth System Science, Natural Catastrophes and Geologic Hazards, Glacial Geology and Records of Climate Change, Geomorphology, and a first year seminar about the Geology of National Parks.
