Staff -> B. Müller-Karulis

I am a research assistant and researcher at the Latvian Institute of Aquatic Ecology since 1997. My main research interest is ecosystem modeling, focusing on the long-term changes in phytoplankton and nutrient pools in the Gulf of Riga
From 2004 – 2007 I was responsible for the Productivity Coordination Center in the Baltic Sea Regional Project (BSRP), funded by GEF/World Bank and managed jointly by HELCOM and ICES. I served as the co-chairs of the ICES Study Group on Baltic Sea Productivity and of the ICES/HELCOM Working Group on Integrated Assessments of the Baltic Sea.
