Gund Postdoctoral Fellow, RSENR

Dr. Andrew Christ is a Postdoctoral Fellow in the Rubenstein School of Environment and Natural Resources at the University of Vermont. He is a glacial geomorphologist interested in the climate history of Earth’s polar regions over the last several million years. To study this topic, he uses a variety of geologic archives ranging from marine sediments collected from the fjords of the Antarctic Peninsula to glacial moraines in the Transantarctic Mountains to sediments recovered from the bottom of ice cores from Greenland.  He uses many field-based and lab methods, chiefly cosmogenic nuclides, to understand how glaciers and climate change sculpt landscapes through time.


Drew’s current research focuses on analyzing frozen sediment recovered from the bottom of the Camp Century ice core from northwestern Greenland. This sediment contains incredibly well-preserved frozen plant fossils from a tundra ecosystem that emerged in Greenland when the ice sheet melted away several times in the past few million years. He is working on this NSF-funded research with Professor Paul Bierman in the UVM/NSF Community Cosmogenic Facility.
