About
Sergei M. Kopeikin is a leading figure in relativistic celestial mechanics and gravitational physics, with a career focused on precision tests of Einstein’s general relativity. His most influential work centers on the orbital and rotational dynamics of the Moon, particularly in the context of sub-centimeter lunar laser ranging (LLR). In his highly cited 2008 paper, Kopeikin outlined the theoretical framework needed to exploit next-generation LLR data, showing how ultra-precise measurements of the Moon’s motion can probe the equivalence principle, constrain gravitational theories, and detect subtle relativistic effects like geodetic precession. This work has been foundational for modern lunar science, accumulating over 30 citations and guiding experimental efforts at observatories such as the Apache Point Observatory Lunar Laser-ranging Operation (APOLLO). Kopeikin’s broader contributions include developing the parametrized post-Newtonian formalism for light propagation and advancing the theory of relativistic reference frames. His research bridges the gap between abstract gravitational theory and high-precision astrometry, making him a key voice in the quest to test gravity at solar-system scales.
