Topics of research

-Dynamical systems and ergodic theory:
I am interested in the study of group actions and random dynamical sysytems on manifolds of small dimension. I am trying to exhibit hyperbolicity phenomena (e.g. study of the Lyapunov exponents), conditions of reduction (e.g. KAM reduction, invariance principles) and structure of group actions (e.g. Markov partitions, Ping-pong structures).

-Functional analysis in probability:
I am working in the study of non linear functionals of random variables by the mean of functional calculus technics (e.g. Dirichlet and Malliavin's calculus, Wiener's chaos decompositions), in particular to establish properties of the distribution measures, concentration and anticoncentration phenomena, central limit theorems.

ANR project

I participate the ANR project Gromeov, on the study of group actions on manifolds of small dimensions, supervised by Michele Triestino and Victor Kleptsyn.


I organize the analysis seminar of the LAMA with Colin Petitjean [page]
