Research description – Publications – Resume
Thanks for visiting my webpage! I Professor and Chair of the Department of Mathematics at Brandeis University, and Faculty in the Volen National Center For Complex Systems and in the Neuroscience Graduate Program at Brandeis University. Previously (see my Resume), I was group-leader at Collège de France, in the heart of old Paris, and my lab was hosted in the Center for Interdisciplinary Research in Biology. Even before this, I was a postdoc in the Department of Mathematics at Pittsburgh University, under the mentoring of Bard Ermentrout, and at the Mathematical Physics laboratory of the Rockefeller University in New-York (2010) working with Marcelo Magnasco. I performed my PhD in applied mathematics at Ecole Normale Supérieure (Paris) and INRIA, and obtained my PhD degree in Math and Applications from École Polytechnique.
My work (see Publications list) deals with mathematical modeling and mathematical analysis of dynamical systems and stochastic processes. I am passionate about mathematical modeling in biology, and fascinated by neurosciences, ecology and embryonic development in particular. I particularly like to investigate the role of randomness in these processes.
This led me to study how stochastic neural activity can yield regular dynamics in the brain, but also to study models of plasticity mechanisms, which are the elementary elements of how we learn and acquire new skills. But also, models of Parkinson’s disease and its treatments.
When I'm not working, you'll find me enjoying time with my daughter and wonderful family, fixing a random radio or oscilloscope from the 20s-50s, or restoring, fixing, tuning and riding a random antique rusty moped.
