Welcome to my webpage! I am currently assistant professor (maitre de conference), in Universite Rennes 1, France. My main reserch area is at the intersection of probability, geometry and mathematical physics, with a particular interest in the study of hypoelliptic diffusions, including a class of diffusions intrinsically associated with any relativistic spacetime, called relativistic diffusions. I have also been involved in the study of Smoluchowski coagulation equation (homogeneous or not), which describes the macroscopic evolution of some interacting particle system. I have recently developped a personal approach of rough paths which offers numerous perspectives, to the study of stochastic flows of maps and homogenisation problems in particular. I have also started looking at some problems on singular stochastic PDEs, developing the paracontrolled approach to the subject.
