I am a graduate of Moscow School for Mathematics No 2 (web site in Russian), class of 1981

PhD received in 1989 from Moscow State University

Curriculum vitae , Research statement, (documents in French)

Areas of interest:

differential geometry, algebra, integrable systems;

cohomology of Lie algebras of vector fields and diffeomorphism groups;

Virasoro algebra and its generalizations;

graded commutative algebras.

Together with Christian Duval and Pierre Lecomte we developed equivariant quantization,

I am on the Editorial Board of Journal of Nonlinear Mathematical Physics

You can download a preprint version of my book with Sergei Tabachnikov
