My research work lies within the scope of statistical physics and is devoted in particular to the study of non-equilibrium systems.
A word on the problematic...
Although the statistical properties of systems at thermal equilibrium are generally well understood theoretically, it is far from being the case out-of-equilibrium. This is all the more deceptive than equilibrium is rather the exception than the rule in nature. The theoretical understanding of non-equilibrium systems and in particular of non-equilibrium critical phenomena appears as a one of the major challenges of statistical mechanics nowadays. Making progress requires the development of new theoretical tools. In this respect, the framework of field theory, and more specifically non-perturbative renormalization group methods (initially developed in the nineties for high-energy physics) stand as promising candidates to investigate the rich physics of non-equilibrium systems and they are part of my field of expertise.
