I am a member of the Soft Matter group in the Department of Applied Mathematics and Theoretical Physics.

My current research interests focus on large deviations theory, its applications to glassy dynamics and notably to the study of phase transitions that may control the dynamics of glass former systems.

Other research interests include large-scale, effective, stochastic descriptions of nonequilibrium systems and how one can use them to describe macroscopic phases and thermodynamic behaviors. In particular, I have been interested during my Ph.D. in the dynamics of the overall densities of two nonequilibrium steady state systems brought into contact and how one can infer from it possible nonequilibrium chemical potentials (and effective free energies).
