Keywords: quantum field theory, particle physics, cosmology, mathematical physics

I obtained Ph.D. degree in Physics from the Moscow State University in 1983.
Research interests during last years:
- multidimensional (Kaluza-Klein type) theories
- multidimensional cosmological models
- exact renormalization group approach
- 2D Yang-Mills theories
- instanton-induced high energy processes of elementary particles
