• PhD (Candidate of physical-mathematical sciences), Ioffe Inst., 1969
• Habilitation (Doctor of physical-mathematical sciences), Ioffe Inst., 1984

My main research interests are related to physics of neutron stars, radio pulsars, X-ray pulsars, and general relativity. Recently I completed investigation of general relativistic electrodynamics of  rotating neutron stars (in collaboration with A.Muslimov) and acceleration of  X-ray binaries by their own radiation (an effect of photon rocket) (in collaboration with V. Pal'shin).
