Gilles Lepoint (ORCID: 0000-0003-4375-0357), senior permanent Researcher at FNRS, is a zoologist and marine biologist, broadly interested in marine biodiversity, in trophic ecology of animals, in structure and functioning of food webs, and their anthropogenic perturbations.  Most of his work focused on the use of stable isotopes of light biogenic elements (integrative descriptors of consumer diet) to delineate trophic interactions in ecosystems (marine, freshwater and terrestrial) and trophic ecology of animals. Gilles Lepoint currently leads the laboratory of trophic and isotope ecology (LETIS) and manages University of Liège's stable isotope facility (two IRMS, renewed in 2020). During his PhD and his post-doctoral work, he has mainly focused his research on seagrass ecology. Since 2006, he has developed a personal project on the animal communities associated with seagrass macrophytodetritus accumulations. Since 2014, he and his group have been involved in Austral ocean food web studies and anthropogenic effect on biodiversity and trophic ecology (vERSO, RECTO, TANGO, Brain-BE projects, BELSPO, 2014-2025). Involved in marine tropical ecology since 2010, he has obtained in 2017 a project, funded by the FNRS, on black coral ecology and conservation in Madagascar. Since 2019, he is co-director for ULiège of the marine and aquaculture research station of Belaza (Toliara, MAdagascar), co-managed by the University of Mons (Prof I Eeckhaut) and the University of Tolirara (IHSM, Prof Gildas Todinanahary)
