Henri Berestycki

Henri Berestycki ( born March 25, 1951 in Paris ) is a French mathematician who deals with financial mathematics and partial differential equations.

Berestycki attended from 1971 to 1975, the Ecole Normale Superieure (ENS ) in Paris and in 1975 at the University Pierre and Marie Curie at Haim Brezis doctorate ( Doctorat de 3e cycle, Contributions à l' étude of problèmes elliptiques non linéaires ). As a post - graduate student, he was from 1975 to 1977 Dickson Instructor at the University of Chicago. After that, he conducted research from 1975 to 1983 for the Centre national de la recherche scientifique (CNRS ) as Attaché and later Chargé de Recherche, 1981 habilitated in Paris and was from 1983 to 1988 professor at the University of Paris -Nord and from 1988 to 2001 at the University of Pierre and Marie Curie ( a member of the Laboratory for numerical Analysis Jacques -Louis Lions ), where he also taught at the ENS (Professor 1994-1999 ) and the Ecole Polytechnique ( Maître de conference 1987-1999 ). He also went into the financial industry as a consultant to the Caisse des Dépôts et Consignations (CDC ), the Crédit Commercial de France (CCF ) and HSBC in Paris. In 2001 he was at the École des Hautes Études en Sciences Sociales ( EHESS ) in Paris, where he is Director of the Centre for Mathematics and modeling in the social sciences. Since 2010, he also directs the Program for Financial Mathematics at the University of Chicago. He is in Chicago visiting professor of mathematics and co- director of the Center Stevanovich of Financial Mathematics.

In addition to financial mathematics, he also deals with mathematical modeling in physics and biology ( for example Reaktons -diffusion equations ) as well as in the social sciences and worked on nonlinear partial differential equations (including with Louis Nirenberg )

In 2004 he was awarded the Sophie Germain prize and the Gay - Lussac- Humboldt Prize. In 2010 he was inducted into the Legion of Honor. 2013 Berestycki was elected Foreign Honorary Member of the American Academy of Arts and Sciences. He is a Fellow of the American Mathematical Society.

His PhD is one of Frank Merle.
