Renaud Raquépas

I am a postdoctoral reasearcher in mathematics at CY Cergy Paris Université (Laboratoire AGM), working with Professor Armen Shirikyan. I completed my PhD in late 2020 at McGill University (Department of mathematics and statistics) and Université Grenoble Alpes (Institut Fourier), under the joint supervision of Professors Vojkan Jakšić and Alain Joye. Prior to this, I was an MSc student under the supervision of Professor Jakšić at McGill University, where I also did my undergraduate studies.

Research interests

I study mathematical physics, with emphasis on time-dependent aspects of statistical mechanics and entropy production, in both quantum and classical systems. Relevant mathematical tools to study such problems include operator theory (spectra, resolvents, perturbation theory, one-parameter semigroups), dynamical systems and ergodic theory (mixing, theory of C*-algebras, random dynamical systems), and probability theory (stochastic differential equations, large deviations).
