I study the impacts of anthropogenic activities (e.g. eutrophication, climate change, overfishing, invasive species) on the functioning of marine benthic communities.

The theme of my research is to understand the processes and mechanisms that regulate the structure and functioning of marine benthic systems, with particular emphasis on how human activities transform them. My research focuses mainly on seagrasses and macroalgae which have a fundamental role as habitat-forming species and perform key ecological functions at the land-sea interface. A significant part of my work studies the ecological consequences of overfishing, eutrophication, climate change and the introduction of non-native species on modifying different aspects of trophic interactions (predator – prey, plant – herbivore), because these interactions are fundamental in determining ecosystem structure and function as well as species evolution.
