My research interests are on the margin between biotic and abiotic factors shaping biogeochemical cycling in glaciated catchments. We try our best to find and better describe links between microbial communities or specific organisms and processess with ecological significance on catchment-scale and larger. The biogeochemical processes in glacial catchments provide an exciting opportunity to study a relatively simple community dominated by microbes, which allows us some times to formulate more complex hypotheses. In the last two years I work on a project aiming for better understanding of spatial patterns in microbial diversity using the Greenland ice sheet ablation zone as a model habitat providing possibility of comparing different spatial scales.

I also have interest in photography and graphics. See my photoblog.
