Raphaël is a Postdoc fellow at the Cornell Lab of Ornithology. He is fascinated by the sheer number of birds migrating and their ability to navigate space and maintain perfect timing. He works on modelling and quantifying nocturnal bird migration using weather radar data. Drawing on geostatistical methods, he studies spatio-temporal patterns of bird migration, and, inspired by his background in Hydrology, explores ways to model mass bird migration as a fluid flow, quantifying nightly take-off and landing fluxes of take-off.
