     Current interests: Studies of the models of formation and evolution of the Solar System.

     Previous experience: Specialized in computer simulations of the orbital evolution of celestial bodies (i.e., planetesimals, comets, asteroids, trans-Neptunian objects, and planets) and dust particles in the Solar System, in N-body simulations of the accumulation of planetary objects, and in understanding the processes of the formation and evolution of the Solar System. Studied the accumulation of planets, the asteroid and comet hazard to the Earth, the formation of the Kirkwood gaps, the zodiacal cloud, the Moon and satellites of minor bodies, etc. The studies were based on computer simulation results and on analysis of observations.

     Compared the exoplanet detection capability of microlensing observations for several telescopes and several models of a choice of microlensing events selected for observations; analyzed models for sky brightness and seeing (2011-2013). Analyzed the images made during the flight of the Deep Impact spacecraft to Comet 9P/Tempel 1 (2005-2010). Applied the FLASH adaptive mesh refinement hydrodynamics code to study the dynamics of mixing and transport processes in the presolar cloud (2006-2007). Studied the radiative transfer in atmospheres of test extrasolar planets (2007-2008).

     Conducted observations of asteroids (1999). Studied non-astronomical problems, e.g., the acoustic wave generation at filtration of fluids in porous rocks (2001), the channel routing for two-layer microchips (1985-1990).

     Worked together with John Mather (a Nobel Prize in Physics laureate), Michael A’Hearn (the principal investigator for the NASA EPOXI and Deep Impact missions), Alan Boss (a prominent scientist in stellar and planetary system formation), Eric Elst (a discoverer of over 3,000 asteroids), Timur Eneev and Michael Marov (Russian academicians, pioneers of space flights), Keith Horne (a prominent scientist in search of exoplanets and several other astronomical problems), etc. Scientific interests are presented in more detail on!144&parId=C67D93A65F0A2A17!127&app=Word (scientificinterests.doc).

     PROGRAMMING: Wrote codes in FORTRAN and IDL. Worked in LINUX and WINDOWS. Prepared papers with figures in tex, ps, pdf, and doc, presentations in ppt, and movies in mpeg.
