I was born on December 5th, 1955.

I studied from 1974 to 1978 at Ecole Normale Supérieure, Paris, and from 1978 to 1979 at Princeton University, NJ, USA.

From 1981 to 2000, I worked as CNRS researcher in the Centre de Physique théorique at Ecole Poytechnique.

Since 2001 I am professor in the physics department of University Paris-Sud XI at Orsay, France.
