My field of research is gravitation and general theory of relativity. I am interested in phenomena predicted by this theory like black holes and gravitational waves and also in the ways of testing these predictions. Presently my scientific work is focused on theoretical and practical aspects of analysis of data from gravitational-wave detectors. Ground-based detectors of gravitational waves are currently working in Germany, France, Italy, Japan, and the USA. NASA and the European Space Agency are planning to put a gravitational wave detector (LISA project) in an orbit around the Sun.
