Specialization and most important results: Numeric treatment of observed data, especially of astrometric observations of Earth rotation parameters (smoothing method), orbital motion of the Moon and rotational dynamics of the Earth (tidal and rotational deformations, planetary effects in precession-nutation, atmospheric excitation of polar motion and speed of rotation), cooperation on linking the Hipparcos Catalogue to extragalactic system, calculation of ephemeredes of celestial objects, combination of Earth orientation parameters by different space techniques, derivation of astrometric star catalogues from combination of Hipparcos and ground-based observations, studies of geophysical excitations Earth orientation. About 300 scientific papers published.
