G.-H. Cottet's home page

Welcome to my home page.

I have been Professor at the Université Joseph Fourier since 1990 and senior member of the Institut Universitaire de France since 2009.
I was previously Research Assistant at CNRS and Assistant-Professor at UCLA.

I am a member of the PDE team. My research is in Numerical Analysis and Scientific Computing.

I was chairman of the LJK from its creation to 2010. I was the founder in 2011 and chairman until October 2104 of AMIES, a national initiative of CNRS with INRIA and University of Grenoble, to foster interactions between mathematics and enterprises.
