Key Areas of Graduate Supervision

Remote sensing and modeling of northern lakes and permafrost, lake-atmosphere interactions.

Recent Courses Taught

GEOG 271: Earth from Space Using Remote Sensing

GEOG 320: The Cryosphere

GEOG 602: Remote Sensing of Cold Regions

Research Interests
My main research interests are in remote sensing and modeling of cold regions with the intent of deepening our knowledge, understanding and predictive capabilities of lake/land-atmosphere/climate interactions. Some of my current areas of interest include the development of satellite-based lake and permafrost-related products, the response of lakes to contemporary and future (projected) climate conditions, the role of lakes in weather, and improvement of the representation of cryospheric processes in lake model schemes as implemented in numerical weather prediction and climate models.
