I am a community ecologist, interested in examining the natural and human-mediated processes affecting the diversity, structure and functioning of marine habitats and associated communities. My expertise encompasses various fields, especially taxonomy, sampling design, data analyses and ecological theories. My current research focusses on the interactions among communities and ecosystems across natural and urban seascapes, at multiple scales.

Currently ongoing, my main project (Kelp me !) is related with marine urbanization, which causes important change to the marine environment. As they proliferate at sea, artificial infrastructures are colonized by novel assemblages and generate novel species interactions. Besides providing a better understanding into the biotic and abiotic factors that influence the distribution of these organisms, Kelp me ! is paying a particular attention into the putative influence of foundation species, including kelp and other seaweeds. In particular, the project is addressing whether certain interactions (habitat formation, nursery role, transfer of microbiota, feeding relationships) between species take place in these novel assemblages and to what extent they affect the functioning (e.g. gas and nutrient fluxes) of these neo-ecosystems.
