The Candidate of Science Degree (Ph.D.
degree equivalent) in physics and mathematics he got from the Kharkiv National University in 1978.
The Doctor of Science Degree in physics
and mathematics he got from the Kharkiv
National University in 1988.
He
is recognized as an expert in the fields of radio physics and mathematical
physics. He has also experience in teaching fundamental andapplied mathematics and

Research
interests
Wave scattering theory, analytical
and numerical techniques for wave motion simulation, resonance phenomena,
spectral theory of open structures, operator theory and its applications.
Semi-analytical methods for solving diffraction problems of the resonant
theory of gratings and the spectral theory for open periodic and waveguide
resonators have been developed. Efficient semi-analytical and numerical methods
for the analysis of transient processes under resonance conditions in gratings
and waveguides have been elaborated.
