This is an ongoing series of Summer Training Courses in Experimental Aging Research held yearly in June (supported through 2012). In 2012, the 5-day Course will be directed from the Buck Institute for Research on Aging in Novato, CA. The conference site rotates among three host institutions: The Buck Institute, the University of Texas Health Science Center at San Antonio, and the University of Washington in Seattle. Similar courses have been held with great success every summer since 1993.
