David Quéré is senior scientist at CNRS and joint professor at the École Poytechnique. His research field is interfacial hydrodynamics, ranging from surface coating to wetting of textured surfaces, self-propulsion or biomimetism. His work is motivated by scientific curiosity (superhydrophobic leaves, bird feeding or underwater spiders), but it is also strongly influenced by industrial applications (glass manufacturing, food processing, anti-adhesive coatings). His approach is based on elegant experimental setups and a description of physical phenomena through scaling law arguments. He received the CNRS silver medal in 2014 for his worldwide impact in the development of interfacial hydrodynamics.
