Biosketch


I am a faculty member at  College of the Atlantic (COA) in Bar Harbor, ME where I've taught a variety of Earth Science courses since 2012. Prior to coming to Maine, I worked as an Assistant Professor at McGill University in Montreal following my graduate work at the University of California, Santa Cruz and undergraduate degree at Hamilton College. I grew up in upstate NY and spent a few years in Atlanta, GA working as a Geologist at an environmental consulting firm and as an ECOWATCH AmeriCorps team member. I am trained as a geomorphologist/geochronologist and study the rates and styles of processes shaping the surface of the Earth. 

Research interests

The interactions of climate and tectonics, especially regarding the formation and degradation of orogens, is an active area of research that far reaching implications for how we interpret the forces responsible for the dramatic topography of ranges such as the Himalaya, Andes, and Cordillera of Western North America. My work focuses on understanding the paleoclimatic and neotectonic history of Pleistocene landscape development by using cosmogenic isotope concentrations and low temperature thermochronology to establish the rates of surface processes, such as erosion rates, as well as the chronology of landscape development. My ongoing research projects span topics in mountain building, past glaciations, active faulting, and the erosion of landscapes, many focused in the Andes of South America. Currently, I am working to complete a chronology of past glaciations in a portion of the northern Peruvian Andes in addition to a few new local projects including geologic and geomorphic surveys of MDI watersheds and bedrock and surficial mapping nearby islands.
