Brief description of the main scopes: 

I am an aquatic ecologist with a solid background in phytoplankton ecology and taxonomy. I am expert in phytoplankton functional classifications. Currently, I am eager to link ecosystem functioning to functional diversity (BEF) in planktic algal assemblages of lakes and rivers and quantify the food quality effect of chytrid algal parasites at the phytoplankton-zooplankton interface in pelagic food webs.

Main profile in keywords: 
community ecology, biodiversity—ecosystem functioning, phytoplankton, chytrid algal parasites
