Research interests: This research activity focuses on algal acclimation to light. The main goal is the understanding of the functioning of the photoprotective xanthophyll cycle in micro-algae and its role in the regulation of the primary productivity. One question regards the activation and efficiency of the xanthophyll cycle in response to light variations due to mixing.
Current Projects:
Algal photophysiology: interactions with the environment and biotechnological applications
