Scientific Advisory Board

Dr Bruce AmesDr. Bruce N. Ames, Ph.D. is a renowned scientist with a distinguished academic background, and a Juvenon co-founder. He is a Professor of Biochemistry and Molecular Biology at the University of California, Berkeley. Dr. Ames is also Senior Scientist, Children’s Hospital of Oakland Research Institute. He is a member of the National Academy of Sciences and he was on their Commission on Life Sciences. He was a member of the board of directors of the National Cancer Institute, the National Cancer Advisory Board, from 1976 to 1982.

Dr. Ames was the recipient of a leading award for cancer research, the General Motors Cancer Research Foundation Prize (1983), a leading award in environmental achievement, the Tyler Prize (1985), the Gold Medal Award of the American Institute of Chemists (1991), the Glenn Foundation Award of the Gerontological Society of America (1992), and the Lovelace Institutes Award for Excellence in Environmental Health Research (1995), the Achievement in Excellence Award of the Center for Excellence in Education (1996), the Honda Prize of the Honda Foundation, Japan (1996), the Japan Prize, (1997), and the Kehoe Award, American College of Occupational and Environmental Med. (1997), the Medal of the City of Paris (1998), the Joseph Priestley Award (1998), and the U.S. National Medal of Science (1998). His over 540+ publications have resulted in his being among the few hundred most-cited scientists in all fields: 23rd most cited (1973-1984).

Professor Ames has been the international leader in the field of mutagenesis and genetic toxicology for over 40 years. His work has had a major impact on, and changed the direction of, basic and applied research on mutation, cancer, and aging. The development of the Ames mutagenicity test as a practical tool for the detection of potential carcinogens has led to its use in over 3000 laboratories and in all of the major drug and chemical companies, where it has had a major influence in weeding out mutagenic chemicals while it is cheap to do so and before they are introduced into commerce. The current research of Dr. Ames’ on cells focuses on the oxidative damage to DNA and its relationship to mutagenesis, carcinogenesis and the degenerative diseases of aging. His main interest is in the prevention of cancer and other degenerative diseases of aging.

Tory HagenDr. Tory Hagen, Ph.D. is Chairman of the Science Advisory Board and co-inventor with Dr. Ames on the patent that Juvenon licensed from the University of California, Berkeley, and co-author with Dr. Ames of Mitochondrial Decay in Aging and its Consequences to the Cell.

Dr. Hagen is a Professor, Department of Biochemistry and Biophysics and Principal Investigator and Jamieson Endowed Chair in Healthspan Research at the Linus Pauling Institute at Oregon State University, Corvallis, OR. Previously Dr. Hagen was a Postdoctoral Fellow and Assistant Specialist Research Scientist in the Department of Molecular and Cell Biology at the University of California, Berkeley. He earned his Ph.D. in biochemistry at Emory University.

Dr. Hagen’s current research is focused on the degenerative diseases of aging, mitochondrial decay in aging, and the impact of nutrients on mitochondrial function.

Dr Flint BealDr. M. Flint Beal, M.D. is professor and chairman of the department of neurology and neuroscience at the Weill Medical College of Cornell University and Neurologist-in- Chief at the New York – Cornell campus of New York Presbyterian Hospital.

Previously, Dr. Beal was professor of neurology at Harvard Medical School was chief of the neurochemistry laboratory and director of the clinical trials unit in the department of neurology at Massachusetts General Hospital (MGH). He received his medical degree from the University of Virginia in 1976 and did his internship and first-year residency in medicine at New York-Cornell before beginning his residency in neurology at MGH. He joined the neurology faculty at Harvard in 1983.

Dr. Beal has authored some 350 articles, book chapters and peer reviews on topics such as oxidative damage in Alzheimer’s and mitochondria research in Parkinsonian patients. He serves on the editorial boards of the Journal of Neurochemistry, the Annals of Neurology, Molecular and Chemical Neuropathology, the Alzheimer’s Disease Review and the Journal of Contemporary Neurology.

His research has focused on the mechanisms of neuronal degeneration in Alzheimer’s disease, Huntington’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS). He has also been working on the development of novel neurochemical assays for assessing oxidative damage for use in clinical trials of new therapies for these disorders.

Ervin EpsteinDr. Ervin Epstein, Jr., M.D. is a leading Dermatologist whose research interests have focused on the molecular biology of inherited and neoplastic skin diseases.

Dr. Epstein is also a frequent speaker and leading writer with papers that have appeared in New England Journal of Medicine and Science. He has also served on the boards of numerous dermatological organizations as well as journals, including American Academy of Dermatology and Journal of Investigative Dermatology and has served as President of the Society for Investigative Dermatology, the world’s foremost organization devoted to research into the biology of the skin.

Currently, Dr. Epstein serves as the Research Dermatologist and Clinical Professor of Dermatology at the University of California, San Francisco and has an active private practice in the San Francisco Bay Area.
