I study carbon cycle dynamics, surface hydrology, and changes in permafrost affected landscapes across Arctic-Boreal regions. My research interests include using satellite remote sensing data to inform terrestrial carbon (CO2, CH4) flux modeling, using information from eddy covariance to improve carbon emission models, and better understanding biogeophysical processes regulating greenhouse gas emissions in northern landscapes. When not in the office, I am usually somewhere in the mountains – backpacking, skiing, or mountain biking.
