Research description – Publications – Resume
Jonathan Touboul is Professor and Chair of the Department of Mathematics at Brandeis University, and finds it strange to speak about himself in the third person!
I am also a member of the Volen National Center For Complex Systems and Associate Faculty in the Neuroscience Graduate Program at Brandeis University.
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.
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 degree in Math and Applications from École Polytechnique.
When I'm not working, you'll find me enjoying time with my daughter and wonderful family, fixing some mid-century tube radio, of restoring, fixing, tuning or riding some random rusty moped from the 1960s or 70s.
