I’m a marine ecologist broadly interested in how food web structure and trophic interactions influence polar (Arctic and Antarctic) and deep-sea (namely hydrothermal vents and cold-water coral reefs) ecosystem functioning and biodiversity. I’m also interested in how natural or anthropogenic environmental variations impact animal feeding, and how ecological plasticity mediates marine benthic invertebrates’ response to change. I mostly tackle those issues by developing approaches based on trophic markers, notably stable isotopes. I’m currently assistant professor at ULiège, where I head the animal systematics and diversity lab.
