Sergei Kopeikin (born April 10, 1956) is a USSR-born theoretical physicist presently living and working in the United States, where he holds the position of Professor of Physics at the University of Missouri in Columbia, Missouri. He specializes in the theoretical and experimental study of gravity and general relativity. He is also an expert in the field of the astronomical reference frames and time metrology. His general relativistic theory of the Post-Newtonian reference frames which he had worked out along with Victor A. Brumberg, was adopted in 2000 by the resolutions of the International Astronomical Union as a standard for reduction of ground-based astronomical observation. A computer program Tempo2 used to analyze radio observations of pulsars , includes several effects predicted by S. Kopeikin that are important for measuring parameters of the binary pulsars, for testing general relativity, and for detection of gravitational waves of ultra-low frequency. In September 2002, S. Kopeikin led a team which conducted a high-precision VLBI experiment to measure the fundamental speed of gravity. He is also involved in studies concerning the capabilities of the Lunar Laser Ranging (LLR) technique to measure dynamical features of the General Theory of Relativity in the lunar motion. He has recently criticized the claims of other scientists concerning the possibility of LLR to measure the gravitomagnetic interaction. Prof. Kopeikin organized and chaired three international workshops on the advanced theory and model of the Lunar Laser Ranging experiment. The LLR workshops were held in the International Space Science Institute (Bern, Switzerland) in 2010-2012.
Kopeikin was born in Kashin, a small town near Moscow in what was then the USSR. He graduated with excellence from Department of Astrophysics of Moscow State University in 1983 where he studied general relativity under Leonid Grishchuk. In 1986, he obtained a Ph.D. in relativistic astrophysics from the Space Research Institute in Moscow. His Ph.D. thesis was advised by Yakov Borisovich Zel'dovich and presented a first general-relativistic derivation of the conservative and radiation reaction forces in the Post-Newtonian expansions of the gravitational field of a binary system of two extended, massive bodies. In 1991, he obtained a Doctor of Science degree from Moscow State University and moved to Tokyo (Japan) in 1993 to teach astronomy in Hitotsubashi University. He was adjunct staff member in National Astronomical Observatory of Japan in 1993-1996 and a visiting professor in the same observatory in 1996-1997. Kopeikin moved to Germany in 1997 and worked in the Institute for Theoretical Physics of Friedrich Schiller University of Jena and in Max Planck Institute for Radio Astronomy until 1999. He had joined Department of Physics and Astronomy of the University of Missouri in February 2000 where he got tenure in 2004.
