I am engaged in teaching activities within the courses:
Algal toxins
Our research group investigates toxin production in filamentous algae and cyanobacteria, focusing on the production, transport and effects in the aquatic environment. Financed by the Board of agriculture and EU, we analyze spatiotemporal variations of algal toxins in mussels from pelagic aquaculture in the Baltic Sea, with the ultimate goal of developing innovative tools for toxin monitoring.

Salmon Health
The health of native salmon populations in both the Atlantic and the Baltic Sea is increasingly concerning. At SLU, I conduct monitoring of salmon reproductive disorder, M74 and strive for developing cost effective and standardized means of monitoring thiamine status.
