Research Overview

I specialize in the dynamics of microbial communities in polar seas. My recent work deals with the structuring role of sea ice for biological processes in Arctic waters. (See sidebar for website links.)

Besides my participation in the U.S. GLOBEC initiative I want to establish a working group on sea ice ecology focusing on the ice-based microbial food web and the coupling of sea ice, pelagic and benthic realms in Arctic waters.
