I am a paleontologist specializing in freshwater vertebrates from tropical Africa. My research aims to reconstruct ancient aquatic ecosystems, water resource availability, and seasonal contrasts in tropical landscapes. I use an interdisciplinary approach combining faunal assemblage analysis, skeletal growth, and isotopic biogeochemistry (δ18O, Δ’17O). I regularly integrate modern and fossil data to calibrate environmental proxies.
My current work focuses on (1) characterizing the spatial diversity of past freshwater ecosystems, (2) developing isotopic approaches to identify water stress and past ecological refugia, and (3) calibrating the use of skeletal growth rhythms in actinopterygians as tracers of seasonal contrasts.
I teach paleontology, comparative vertebrate anatomy, and geosciences.
