# Sergei B. Kuksin

Sergei Borisovich Kuksin (Сергей Борисович Куксин, born 2 March 1955) is a French and Russian mathematician, specializing in partial differential equations (PDEs).

Kuksin received his doctorate under the supervision of Mark Vishik at Moscow State University in 1981. He was at the Steklov Institute in Moscow and at the Heriot-Watt University and is a directeur de recherché (senior researcher) at the Institut Mathématiques de Jussieu of the Paris Diderot University (Paris VII).

His research deals with KAM theory in partial differential equations (i.e. infinite dimensional Hamiltonian systems); partial differential equations involved with random perturbations, turbulence and statistical hydrodynamics; and elliptic PDEs for functions between compact manifolds.

In 1992 he was an invited speaker with talk KAM theory for partial differential equations at the European Congress of European Mathematicians in Paris. In 1998 he was an invited speaker at International Congress of Mathematicians in Berlin. In 2016 he received the Lyapunov Prize from the Russian Academy of Sciences.
