Research Interests
Mapping and modeling of permafrost distribution, active layer and
ground ice conditions in the Arctic and Sub-Arctic. Interaction
between recent glaciers recession, permafrost warming and changes
in runoff. GIS development as a transient numerical simulator of
spatial permafrost dynamics.
