SUMMARY: A scientist with more than 30 years of experience in modeling and interpreting physical processes. Specialized in computer simulations of the orbital evolution of celestial bodies 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. Also analyzed images made during the Deep Impact mission, studied hydrodynamical problems in astrophysics and radiative transfer in atmospheres, conducted observations of asteroids, and lectured on the migration of celestial bodies. Considered other physical processes such as modeling the generation of acoustic waves at filtration of fluids in porous rocks. Author of more than 200 scientific publications including papers in scientific refereed journals.

WORK STATUS: Permanent resident (Green card).

Research associate, Catholic University of America (Washington, D.C.). May 2004 – October 2004.

Visiting senior research associate, George Mason University (VA, USA). May 2003 – April 2004.

National Research Council/National Academy of Sciences Senior Research Associate, NASA/Goddard Space Flight Center. May 2002 – April 2003.

Visiting researcher, George Mason University (VA, USA), July 2001 – April 2002.

Leading scientist, Institute of Applied Mathematics of Russian Academy of Sciences (Moscow), 1997-2001 (formally until December 2003). Senior scientist, 1990-1997. Scientist, 1987-1990. Junior scientist, 1977-1987. Probationer-investigator, 1975-1977.

SCIENTIFIC INTERESTS: Based on computer simulation results, S.I. Ipatov studied different problems of the migration of celestial bodies (i.e., planetesimals, comets, asteroids, trans-Neptunian objects, and planets) and dust particles in the forming and present Solar System, the accumulation of planets, the formation of the Kirkwood gaps, the asteroid and comet hazard to the Earth, etc. Results of the computer simulations were compared with observations. Besides astronomy, Ipatov has an experience in mathematical modeling for several other physical problems (e.g., for the generation of acoustic waves by fluid moving in porous media). During last years, he successfully studied several problems which were quite new for him. In 2006-2008 Ipatov applied the FLASH adaptive mesh refinement hydrodynamics code to study the dynamics of mixing and transport processes in the presolar cloud and in the solar nebular and also studied the radiative transfer in atmospheres of test extrasolar planets. As a member of Deep Impact team, Ipatov analyzed the images made during the flight of the Deep Impact spacecraft to Comet 9P Tempel 1. Since April 2008 Ipatov has been worked at CUA as a PI of the NASA DDAP grant “Velocities and amount of material ejected at different times after the Deep Impact collision”.

PROGRAMING: All Ipatov’s studies were based on computer simulation results, and usually he wrote codes in FORTRAN and IDL by himself. He works both in LINUX and WINDOWS. Ipatov prepared papers with figures in tex, ps, pdf, and doc, presentations in ppt, and movies in mpeg (e.g., using VisIt and xflash).

EDUCATION: Full Doctor of Physical and Mathematical Sciences (this degree is of the scientific level of a full professor), Supreme qualification committee of the Russian Federation, 1997 (Dissertation "Modeling of migration of celestial bodies in the Solar System”).

Candidate of Physical and Mathematical Sciences (equivalent to Ph.D.), M.V. Keldysh Institute of Applied Mathematics, 1982 (Ph.D. Thesis: "Evolution of orbits of gravitating particles and the problem of accumulation of planets in the Solar System").

Master’s Degree. Faculty of Mechanics and Mathematics (Department of Theoretical Mechanics) at Moscow State University. 1970-1975. Different mathematical courses (e.g., Mathematical analysis, Analytical geometry, Highest algebra, Differential equations, Theory of functions with complex variables, Differential geometry, Fundamentals of calculation methods, Theory of probabilities), Celestial and Theoretical mechanics, Fluid mechanics, Stability Theory, Optimal control, Programming, different special courses in mechanics and physics, etc.

PUBLICATIONS: Sergei Ipatov is the author of more than 200 scientific published works, including papers in international refereed journals (Advances in Space Research, Celest. Mechanics and Dyn. Astron.; Earth, Moon, and Planets; Icarus, etc.), in the refereed proceedings of international conferences, in Soviet and Russian refereed journals (translated as Solar System Research, Soviet Astronomy, Soviet Astron. Letters, Kinematics and Physics of Celestial Bodies, Intern. Applied Mechanics, Astron. and Astrophys. Transactions), the book "Migration of celestial bodies in the Solar system" (Moscow, 2000, 320 p., in Russian), etc. A list of publications and texts of most of them are presented on http://faculty.cua.edu/ipatov/list-publications.htm .

LECTURESHIP: Lectures on migration of celestial bodies at the astronomical department of Moscow State University in 1998 (these lectures were published as the book in 2000).

In 2002-2003 Ipatov supervised the work of P. Taylor, who was a summer student in NASA/GSFC in 2002 and 2003. Ipatov taught mathematics at Russian high schools in mid-70s as a volunteer.

Society (2002-), International Astronomical Union (2003-), Russian Academy of Natural Sciences (section of physics, since 2000), Russian Academy of Sciences and Arts (2000-), New York Academy of Sciences (1995-1996, 2004-), American Geophysical Union (2006-), an associate of Committee on Space Research (COSPAR, 1996-). He was a fellow of International Biographical Association in 1998-2001.

Ipatov is a member of the editorial board of the journal “Solar system research” since 2003.

GRANTS. In 2008-2009 Ipatov is a principal investigator of the NASA DDAP grant “Velocities and amount of material ejected at different times after the Deep Impact collision". Ipatov was a principal investigator of grants of the Russian Foundation for Basic Research (RFBR) from 1993 to 1998 and from 2001 to 2003. In 2001-2004 he was a leader of Moscow team of the INTAS grant.

VISITS TO SCIENTIFIC INSTITUTIONS: For one or two months, Ipatov visited Institute for Theoretical Physics of the University of California in Santa Barbara in 1992, Notre-Dame University in Namur (Belgium) in 1995, Berlin Institute of Planetary Exploration in 1996, Royal Observatory of Belgium (Brussels) in 1998, Dresden Technical University in 2001. In 1999 he visited the Royal observatory of Belgium for 5 months. During this visit together with E. Elst and T. Pauwels he found several new asteroids that got numbers. Ipatov made shorter trips to the Department of Terrestrial Magnetism of Carnegie Institution of Washington in 1990, University of London (1995), Armagh Observatory (Northern Ireland, 1995, 2000), Nice Observatory (1999), Inst. d’Astrophysique de Paris (2007), etc. Ipatov delivered lectures at many conferences in various countries.
