About this image

Professor Geoffrey W. Marcy received his B.A. in physics and astronomy from the University of California at Los Angeles in 1976 and his Ph.D. in astronomy and astrophysics from the University of California at Santa Cruz in 1982. Later that year, he became a Carnegie Fellow at The Carnegie Institute of Washington. Dr. Marcy joined San Fransisco State University in 1984, where he is currently an Adjunct Professor of Physics and Astronomy. In 1999, he was appointed Professor of Astronomy at the University of California at Berkeley.

Dr. Marcy's research has focused on the detection of extrasolar planets and brown dwarfs. His team has discovered 145 extrasolar planets (as of Nov. 2007), allowing study of their masses and orbits. Among the planets discovered are the first multiple-planet system, the first Saturn-mass planet, the first Neptune-mass planet, and the first transiting planet. Ongoing work is designed to study the mass distribution of planets and the eccentricity of their orbits. Dr. Marcy is participating in Berkeley's new "Center for Integrative Planetary Science," designed to study the formation, geophysics, chemistry, and evolution of planets.
