My main research interests include glacial and Quaternary geology, paleoclimatology, and geomorphology.
I apply cosmogenic nuclide techniques to develop reconstructions of long-term glacier and ice-sheet change in the Arctic with the hopes of better understanding the sensitivity of the Arctic cryosphere to climate variability.
The leading technique to realize this is the application of terrestrial cosmogenic nuclide.
