Henri Berestycki (born 25 March 1951) is a French mathematician who obtained his PhD from Université Paris VI – Pierre and Marie Curie University in 1975. His Dissertation was titled ''Contributions à l'étude des problèmes elliptiques non linéaires'', and his doctoral advisor was Haïm Brezis. He was an L.E. Dickson Instructor in Mathematics at the University of Chicago from 1975–77, after which he returned to France to continue his research. He has made many contributions in nonlinear analysis, ranging from nonlinear elliptic equations, hamiltonian systems, spectral theory of elliptic operators, and with applications to the description of mathematical modelling of fluid mechanics and combustion. His current research interests include the mathematical modelling of financial markets, mathematical models in biology and especially in ecology, and modelling in social sciences (in particular, urban planning and criminology). For these latter topics, he obtained an [http://erc.europa.eu/advanced-grants ERC Advanced grant] in 2012.

He worked at the French National Center of Scientific Research (CNRS), then moved to an appointment as Professor at University Paris XIII (1983–1985). He became a Professor of Mathematics in 1988 at Université Pierre et Marie Curie, Paris VI (1988–2001 of “exceptional class” since 1993), and became professor at École normale supérieure, Paris (1994–1999), and part-time professor at the École Polytechnique (1987–1999). He is also a visiting Professor in the Department of Mathematics at the University of Chicago, and was also co-director of the Stevanovich Center of Financial Mathematics in Chicago. He is currently the Directeur d'études (Research Professor) at École des hautes études en sciences sociales (EHESS), since 2001. Provided by Wikipedia
