Research Gate


I graduated from the University of Helsinki in 1995 (major subject limnology). Topic of my PhD thesis was “Sediment dynamics of phosphorus in the Gulf of Finland” and I achieved docentship in aquatic sciences in 2009. At present my scientific interest is focused on respiration and redox-reactions and the consequences caused in marine- and lacustrine ecosystems.

Present tasks

My present work is concentrated on solving of eutrophication problems. I plan, lead and carry out co-operative research projects. I act as an expert in the steering groups of national and international projects. I’m also a Research Integrity Adviser together with Helena Valve in our institute.

Present research topics

Nowadays my research is focused on the bioavailability of soil bound phosphorus leaked into lake and coastal waters and effects of climate change on biogeochemistry of lakes. I’m also interested in factors affecting the movement of terminal electron acceptors in aquatic systems and how artificial oxygenation affected physics and geochemistry in coastal basins.
