I have been a development researcher since 2004 and joined IMBE in 2024. I am interested in the functioning of planktonic ecosystems in oligotrophic environments in the Pacific and Mediterranean Seas. My work focuses on the functional group of photosynthetic diazotrophs, which are both major primary producers in these environments and producers of phycotoxins that are harmful to the environment and human health.
