Biography
Sergey Derkachov is leading researcher of the Laboratory of Mathematical Problems of Physics in St. Petersburg Department of Steklov Mathematical Institute of Russian Academy of Sciences. The research activity in the last period of time is concentrated on application of the methods of integrable systems to the problems of the quatum field theory, for example, the multiloop calculations.
