Gary Friedman, MD, MS, is a research scientist emeritus at the Kaiser Permanente Northern California Division of Research; and consulting professor, Department of Health Research and Policy, Stanford University School of Medicine. Dr. Friedman began working at the Division of Research in 1968 as senior epidemiologist, then became assistant director for epidemiology and biostatistics, and served as its director from 1991 to 1998. His research interests include the epidemiology of cancer, cardiovascular disease, and gallbladder disease; the health effects of tobacco, alcohol and medicinal drugs; and the evaluation of screening tests. Dr. Friedman is also an editor of the American Journal of Epidemiology and on the editorial board of the Journal of Medical Screening. From 1989 to 2002 he was supported, in part, by an Outstanding Investigator Grant from the National Cancer Institute. Dr. Friedman served as president of the American Epidemiological Society from 1999-2000; and in 2000, he was awarded a Distinguished Service Award from the University of Chicago s Medical and Biological Sciences Alumni Association. Dr. Friedman s scientific publications number over 300. He was one of the first researchers to conduct extensive epidemiological studies in the setting of a health maintenance organization. More information about Dr. Friedman s epidemiologic career can be found in the Gary Friedman Symposium, published in the Fall 1998 issue of the Permanente Journal, available at:
