His research interests include Alpine geomorphic processes and climates in western North America, New Zealand, Australia, and Central Asia; Ice-core paleoclimatology; Cordilleran Ice sheet and sea-level dynamics; Pedagogy of field and research projects in undergraduate education. Broadly, he studies landscapes and landscape evolution, the processes that shape them, with a particular focus on glaciated regions. He also investigates past variability in climate that accompanied or caused these changes, mostly by combining detailed landscape mapping and analyses with radiometric dating to constrain the timing and rates of those changes. He spent nearly a month on Mount Waddington in British Columbia drilling an ice core for paleoclimate work in 2010 and knows the North Cascades well.
