 Ph.D.
in Physics and Mathematics, associate professor
of the Department of Radio Physics of the University of St.
Petersburg.
Born in 1958 in Estonian Republic (USSR), graduated from the
Faculty of Physics of Leningrad State University
(1980), PhD in Physics and Mathematics (1986). Scientific interests
lie in the field of the numerical modelling of physical processes,
analytical and numerical methods in the problems of wave propagation
in the deterministic and stochastic media, in particular, HF, VHF
and UHF propagation in the disturbed ionosphere, characterization of
the ionospheric and transionospheric propagation channels, satellite
navigation systems (GPS, GLONASS, Galileo).
The
author of 145 scientific publications, co-investigator in many
projects funded from the state budget,
as well as by the grants of Soros (International Science
Foundation), Russian Foundation for Basics Research, Ministry for
Education of Russia, CRDF of USA, EPSRC of the UK, etc. Worked at
the University of Leeds, UK as the Research Fellow in 1999, 2001-02
and 2006-07. Also worked as the Visiting researcher at the
University of Newcastle, UK in 2010. Undertook scientific visits to
the Universities and other scientific institutions of Sweden, Italy,
France, and Great Britain. Participated from the University of St.
Petersburg at the EC COST Actions 251, 271 and 296. Participated at
many Soviet, Russian and international conferences, in particular,
as the invited presenter.
