I generally work on several aspects of marine biodiversity as I have broad natural history interests, but my main focus is on the ecology and evolution of underwater marine caves.

Among cave species, mysid and decapod crustaceans are my main interest, as well as sponges showing deepwater affinities (canyons).

Caves are a convenient model of island-like habitat, well suited for population studies on habitat fragmentation and connectivity.
My research comprises a natural history part to describe communities and their species, including when they are new to Science, but also an evolutionary side, devoted to molecular phylogeography and phylogeny.

I am also looking at the effects of global change on these poorly resilient communities, particularly as regards ocean warming.
My study areas are mostly located in the Mediterranean, but I find useful to campare patterns across geographical regions and have therefore also worked in the Atlantic (nearby and Caribbean), Pacific (Marquesas) and the Antarctic (Adélie Land).
