Malo Jézéquel
I am a "chargé de recherche" at CNRS, based at LMBA in Brest. Before that, I was a C.L.E. Moore Instructor at MIT and even before a PhD student under the supervision of Viviane Baladi. For further details, you may refer to my curriculum vitae.

Research interests
I study statistical properties of hyperbolic dynamical systems by functional analytic methods. Doing so, I developed an independent interest for PDE techniques, such as microlocal analysis, in particular in the context of high regularity (real-analytic, Gevrey, ultradifferentiable,...). During my PhD thesis, I addressed the question of trace formulae for uniformly hyperbolic dynamics.
