In May 1991, Dr. Penhoet received the first Distinguished Faculty Award from the Life Sciences Department of Molecular and Cell Biology at the University of California, Berkeley. In 1992, Dr. Penhoet shared with Dr. William J. Rutter, a Chiron co-founder, the Northern California Entrepreneur of the Year Award presented by Ernst & Young and Inc. Magazine; in 1994, they received jointly the Harvard Business School Northern California Alumni Chapter award as Entrepreneur of the Year.
Dr. Penhoet is Chairman of the California Health Care Institute, Oakland Museum Foundation, and a member of the National Research Council. He is a member of the Boards of Directors of the California Business Higher Education Forum, Biotechnology Industry Organization, the Bay Area BioScience Center, the Bay Area Council, the California Public Health Foundation, the Chabot Observatory and Science Center Foundation, the UC System Biotech Advisory Committee, , Onyx Pharmaceuticals, the UC Berkeley ChancellorÕs Biotechnology Planning Board and the Advisory Board for the Lester Center for Entrepreneurship and Innovation at UC Berkeley.
