Resume Research Statement

Research interests


I am mainly interested in statistical physics and its broad applications to biology, population dynamics or finance. My PhD subject tackle emerging collective properties in active matter but I have also worked on explore-exploit paradigms and on stochastic thermodynamic. Active Matter describes systems extracting energy from their environment at the microscopic scale, thus driving them far from equilibrium. Activity is encountered at all scales in nature, from molecular motor to flies swarm, passing through the canonical examples of swimming organisms (bacteria) or artificial swimmers (Janus colloids). The physics exhibited by such systems is very rich, often displaying a wealth of emerging collective properties and achieving complex cohesive states of matter. The main goal of my PhD is to theoretically elucidate how active particles reach such an intricated, large-scale structure.

Teaching experiences


So far, I have mainly given lectures in the medicine cursus at Paris Descartes University.
