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 prespectives
Current
Research Programs:
1) BNZ-LTER,
2) Continued monitoring of a 35-year forest growth
study,
3) Re-programing of the SAFED model to visual basic
in the ArcMap framework,
4) Setup and monitoring of longterm 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
