ABOUT ME: I'm a Quaternary geologist who uses stratigraphic, paleoenvironmental, and geochemical approaches to address research questions related to landscape and climate change in the north. Timescales of interest range from the early Cenozoic to the late Holocene. I have ongoing interests in developing records of landscape and environmental change in unglaciated northwest North America, permafrost and ice-sheet response to sustained climate warming during Pleistocene interglacials, and Cenozoic analogues for contemporary warming. I'm also interested in studying modern glacier and permafrost change.

I am interested in developing stratigraphic, geomorphic, and geochemical records of northern climate change and associated earth system impacts. My work and research interests span timescales ranging from millions of years to the last several centuries, with a particular focus on periods when climate was similar to or warmer than today, such as Pleistocene "super-interglacials" and Cenozoic greenhouse intervals.
