Personal profile

Description of research and teaching

My research interests lie in the field of marine biogeochemistry, with a focus on elemental cycling in coastal systems, biogeochemical responses to anthropogenic pressures, and, particularly, benthic nitrogen turnover. Excess availability of land-derived nitrogen in coastal waters has led to coastal eutrophication all around the world, including the Baltic Sea; at the same time, elemental turnover processes in the coastal zone can temporarily retain and permanently remove nitrogen, thereby mitigating its transport to open waters. Understanding nitrogen turnover in the coastal habitat is thus imperative for understanding its fate in the wider marine system.

 

Research projects:

Elucidating seasonal substrate limitation of benthic nitrate reduction in the coastal Baltic Sea (PostDoc: Walter and Andrée de Nottbeck Foundation, 2020-2021)

Biogeochemical links between eutrophication and climate change in the Baltic Sea (PhD student: Academy of Finland, 2013-2018)

BONUS COCOA - Nutrient cocktail in coastal zones of the Baltic Sea (PhD student: funded jointly by the EU and the Academy of Finland, 2014-2017).
