My research in the Arctic
High Arctic thermokarst development
This study combines permafrost borehole measurements, climate data, and repeat field surveys to explore the environmental factors and mechanisms driving rapid and widespread thermokarst development in very cold permafrost (MAGT of -14°C at 1 m depth) in the Canadian High-Arctic.

How Arctic landscapes will respond to climate change will depend in part on Pleistocene legacy effects. This study used remote sensing and field surveys to explore how landscapes underlain by a range of Quaternary Geology units respond differently to climate change.

Arctic Coastal Dynamics
Sea ice is declining at approximately 10 % per decade. This is expected to make Arctic coastlines more dynamic. This study uses remote sensing to explore coastal dynamics between 1950 and 2014 in NW Alaska.

Pleistocene Arctic Ocean Glaciation
Coastal surveys, Bering Land Bridge NP, Alaska
One of the best sources of information about how future climate change might affect the Arctic comes from understanding what happened in the past. This study utilizes sedimentological and stratigraphic analysis in combination with optically stimulated luminescence dating to explore how late Pleistocene marine deposits can inform us about past Arctic Ocean glaciation.

Thermokarst lake development
Thermokarst lakes play an important role in the Arctic carbon cycle. We conducted sedimentary analysis on a suite of lake cores from the Seward Peninsula, Alaska, to better understand the stages of lake formation.
