Research Interests

Dr. Bob Reedy’s research uses the products of cosmic-ray interactions to study matter and radiation in the solar system. Cosmic-ray-produced nuclides are used to study the recent histories of interplanetary energetic particles and of lunar samples, meteorites, and terrestrial-surface samples. Gamma rays were used to determine the elemental composition of the top meter of Mars and the Moon as well as 4/Vesta and 1/Ceres.

Professional History

Dr. Reddy received his PhD in Chemical Physics in 1969 from Columbia University. After spending a few years as a Postgraduate Research Chemist at the University of California, San Diego, in 1972 he joined the technical staff of Los Alamos National Laboratory. In 2002, he became a Research Professor at the Institute of Meteoritics at the University of New Mexico. During the Apollo program, Dr. Reedy was Lunar Sample Co-Investigator (1969-1976) and a Co-Investigator on the Apollo Gamma-Ray Spectrometer Experiment (1970-1974). He was on the Mars Observer Gamma-Ray Spectrometer Team (1986-1993). He was on the Long Duration Exposure Facility (LDEF) Radiation Analysis Team (1990-1993). He was on the DOE’s Lunar Scout Gamma-Ray/Neutron Spectrometer Team (1992-1993). He was on the Mars 1996 (Russia) Precision Gamma-Ray Spectrometer Instrument Team (1994-1996). He was on the NASA/ESA Rosetta Mission Champollion Lander Gamma-Ray Team (1995-1996). He was a Participating Scientist on the Near Earth Asteroid Rendezvous Mission (1999-2001). He was Deputy Team Leader for the Mars Odyssey Gamma-Ray Spectrometer (2000-) and was Co-Investigator on the Kaguya (JAXA SELENE program) Gamma Ray Spectrometer (2006-). Dr. Reedy joined the permanent science staff of PSI in 2008.
