Research description – PublicationsResume

Hi there!

My name is Jonathan Touboul, I am Associate Professor at Brandeis University in the Math Department and in the Volen Center for Complex Systems.

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 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. In other words, I spend most of my time working on nonlinear dynamical systems, stochastic processes and interacting particles systems.

Previously (see my Resume), my lab was located at Collège de France, in the heart of old Paris. We were part of the Center for Interdisciplinary Research in Biology. Even before, I was a postdoc in the Department of Mathematics at Pittsburgh University, under the mentoring of Bard Ermentrout, and then for few months in the Mathematical Physics laboratory of the Rockefeller University in New-York (2010), where I was mentored by Marcelo Magnasco. I performed my PhD in applied mathematics at Ecole Normale Supérieure (Paris) and INRIA, and obtained my degree in Math and Applications from École Polytechnique.
