Welcome to my webpage! I am currently professor in the Université de Bretagne Occidentale, France. My main reserch area is at the intersection of probability, geometry and mathematical physics. Recently I have mainly been working on problems involving rough paths, singular stochastic PDEs and Euclidean quantum field theories. I keep a particular interest in the study of hypoelliptic diffusions, including a class of diffusions intrinsically associated with any relativistic spacetime, called relativistic diffusions.
