Short bio

I received a Ph.D. in Computer Science (december 2001) from Université Henri Poincaré, France, INRIA Lorraine. After spending two years at UC Berkeley and LBNL as a postdoctoral researcher, I have joined INRIA in january 2004. I was a member of Sage group at INRIA Rennes and Grand-Large group at INRIA Saclay - Ile de France and LRI, Paris 11 University. Since January 2013 I am leading Alpines, a joint group between INRIA Paris - Rocquencourt and J.L. Lions Laboratory, UPMC.

During the academic years 2014/2016 I am on a sabbatical leave / long mission at UC Berkeley.
