I am an ecosystem ecologist specialized in vegetation-climate interactions in northern ecosystems. I like to combine field studies with ecosystem modelling. Current research focuses on how vegetation influences permafrost thawing and vice versa. Together with PhD candidates and thesis students I also investigate the possibility of shrub decline due to small-scale permafrost collapse instead of the widely reported shrub expansion in tundra ecosystems. At a Siberian tundra site we run field experiments in which vegetation or thawing depth is manipulated.
