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.
