I am a geoscientist interested in how the methods and principles of geology can be used to understand and solve some of the most pressing challenges facing human societies today.  My students and I have a broad range of interests, including the evolution of earthquake-generating fault zones in New Zealand and California, the uplift of mountain ranges in Patagonia and elsewhere, the causes and consequences of large landslides and rockfalls in Vermont, and the spread of PFAS contamination in bedrock aquifers beneath local towns.  Most of my work is field-based where I travel to carefully selected sites in Vermont and around the globe to learn as much as I can about the architecture and temporal evolution of geological features and landscapes.  I also have expertise in the disciplines of continental tectonics and Earth deformation, and the application of UAS (drone) surveys, photogrammetry, and 3-D digital modeling to geologic problems.
