Research

I am Postdoc (since October 30th 2017) at the Los Alamos National Laboratory. I am part of the Advanced Network Science Initiative (ANSI) group under Michael (Misha) Chertkov supervision.

My general research field is theoretical physics with a particular focus on statistical physics of out-of-equilibrium system and nonlinear dynamics.
During my PhD I studied bifurcation in kinetic equations describing that type of systems. Bifurcations in the Vlasov equation (describing for example plasma, self gravitating systems, some cold atom systems) and the Kuramoto model (for coupled oscillators) as well as some "extensions" were the main focus of my PhD.
For my Postdoc I am studying statistical behavior of large aggregates of Thermostatic Constrolled Loads (TCLs), e.g. Air conditionners, Fridges. Basically, we want to improve the resilience of these aggregates by "coupling" the TCLs (in a realistic fashion). The objective being that if these systems are resistant to perturbations, one could use their flexibility and their thermal energy storage for Demand Response.

I did my PhD from October 2014 to September 2017 at Laboratoire Dieudonné, Université Côte D'Azur. My thesis advisor was Julien Barré. You can find here my PhD thesis.
