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 couple ecosystem functioning to functional diversity (BEF) in planktic algal communities of lakes and rivers in a mechanistic way; also to study the importance of Chytrid parasites and their zoospores in the coupling of zooplankton and phytoplankton in aquatic food webs.

Main profile in keywords: 
phytoplankton ecology, community ecology, functional diversity, biodiversity-ecosystem functioning (BEF), Chytrid parasites
