The Berkeley Geochronology Center (BGC) is a non-profit geochronology research institute in Berkeley, California. It was originally a research group in the laboratory of geochronologist Garniss Curtis at the University of California, Berkeley.[1] The center is now an independent scientific research institute with close Berkeley affiliations and directed by geologist and geochronologist Paul Renne, a professor in residence in the department of earth and planetary science at Berkeley.
