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 Junior Researcher 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. From
2011 to 2014 I was coordinator and chairman of AMIES, a national
initiative of CNRS with INRIA and University of Grenoble, to foster
interactions between mathematics and enterprises.
