About Me

I am a Senior Research Associate in the School of Mathematics at the University of Bristol, working with Anthony Lee and Chistophe Andrieu. Before that, I did my PHD at INRIA Paris and Aix-Marseille Université, under the supervision of Laurent Massoulié and Charles Bordenave, followed by a postdoc at KTH, in the team of Alexandre Proutière.

My research focuses on mixing times of Markov chains, notably on the so-called cutoff phenomenon, which is the abrupt convergence of a finite Markov chain to stationarity. Lately, I have started investigating how such concepts can be used to tackle more applied questions, notably in the field of reinforcement learning. Quite generally, I am interested in all kinds of probabilistic and statistical models, as well as stochastic processes and algorithms on graphs.

Here is a short academic CV.

Research Interests: probability theory, mixing times of Markov chains, cutoff phenomenon, random walks on groups, random graphs, reinforcement learning
