On July 15, 1999, The Lawrence Berkeley National Laboratory (LBNL), the University of California, Berkeley (UCB) and BioTime, signed an agreement creating a center for the study of the aging process. The center is now called the Center for Research and Education on Aging (CREA) and is a joint LBNL and UCB institution. Gathered at the signing ceremony are (left to right) Dr. Paul Segall, Dr. Paola Timiras, Dr. Judy Campisi, Dr. Mina Bissell, Dr. Ronald S. Barkin, and Dr. Don McQuade. On November 8th, 2000 the Center for Research and Education on Aging (CREA) opened its doors. The center has a mission to "investigate the basic processes that cause aging, with the goal of improving and extending the human health span." In 2000, Dr. Segall endowed CREA, and with Dr. Paola S. Timiras, M.D., Ph.D. (1923-2008) they established the Center at the University of California, Berkeley. Dr Timiras served as CREA's first chair person from 2000 until she passed away in 2008. The chair is currently held by Dr. George A. Brooks, Ph.D., Professor in the Department of Integrative Biology, at the University of California, Berkeley.
