John Weirich

Dr. Weirich received his Ph.D. in Planetary Science in 2011 from the University of Arizona in Tucson where he was involved in related projects involving geochronology, geochemistry, and diffusion in extraterrestrial rocks (mostly ordinary chondritic meteorites). He was a post-doctoral researcher at Arizona State University, studying geochronology and geochemistry of Apollo 17 samples and granite from Crazy Basin, Arizona. He was a postdoctoral research fellow at the University of Western Ontario where he studied the geochemistry of Sudbury Breccia at the Sudbury Impact Structure, Canada. In 2015 he returned to Tucson and joined PSI to support the OSIRIS-REx mission.
