Research interests

I am a marine biogeochemist interested in benthic nitrogen cycling in coastal systems, biogeochemical responses to anthropogenic pressures, eutrophication dynamics, and ecosystem health. My current research focusses on nitrous oxide cycling in Baltic Sea coastal sediments, the role of organic carbon quality for benthic nitrate-reducing processes such as denitrification and DNRA, and internal nitrogen loading in the Baltic Sea coastal zone. I approach my research via microbial process rate measurements using stable isotope techniques, as well as via micro sensor techniques and porewater biogeochemistry.
