Research interests:
Structure and function of boreal forests, successional processes following catastrophic disturbances, effects of changing environment conditions (including global warming)on forest ecosystem processes, modeling of forest ecosystem dynamics at the ecosystem and landscape perspectives

Current research programs:
2) Continued monitoring of a 35-year forest growth study,
3) Reprogramming of the SAFED model to visual basic in the Arc Map framework,
4) Setup and monitoring of long term log decomposition,
5) Investigation of the effects of summer drought on forest growth,
6) Development of research to study the effects of climate change on boreal forest carbon dynamics

Examples of research support:
"Ecosystem Modeling from a GIS Perspective Applied to Forest Management Decisions Across the Landscape", USDA McIntire-Stennis funding. (2001 - 2006)

"Carbon Cropping the Boreal Forest of Alaska", New Crops III program 2003

"Development of Components of a GIS Based Forest Ecosystem Model Using Visual Basic within ArcGis"' New Crops IV program 2004
