Received Diploma degree (with honors) in applied mathematics in 2002 from the Saint-Petersburg State University (SPbSU, Mathematics and Mechanics Faculty, Department of Theoretical Cybernetics).

In 2002-2006 he was part-time researcher of the Laboratory "Control of Complex Systems" of the Institute for Problems of Mechanical Engineering of RAS.

He is a coauthor of 20 publications.

Research interests: nonlinear control, control of molecular systems, computer modeling of non-equilibrium processes in condensed matter.
