I am a computational and experimental biologist with background in molecular evolution, bioinformatics and biomineralization. I am fascinated by marine biodiversity and have studied evolutionary processes in mollusks, corals and bacteria. In my Marie Skłodowska-Curie project EPIC "Evolution of planktonic gastropod calcification" I am studying the evolution and mechanisms of biomineralization in planktonic gastropods, and how they can cope with ocean acidification.

Biomineralization in planktonic gastropods

Holoplanktonic gastropods (pteropods and heteropods) are among the most vulnerable calcifiers to ocean acidification. They live at the ocean surface and build thin and delicate shells of aragonite, a polymorph of calcium carbonate. My research focuses on the biomineralization genes and mechanisms controlling their shell formation and aims at a better understanding of calcification by marine zooplankton and the impacts of ocean acidification on this process.
