in 1976, he joined what was then the Department of Community and Family Medicine at the University of Southern California (USC) School of Medicine as an instructor. By 1987, he had achieved the faculty rank of professor and, at that time, also began serving as the director of the Los Angeles Cancer Surveillance Program, appointments he held until his death. He was the Flora L. Thornton Chair in Preventive Medicine and the Catherine and Joseph Aresty Professor of Preventive Medicine and Urology at what became the USC Keck School of Medicine. At the time of his death, he was also the deputy director of the USC/Norris Comprehensive Cancer Center and head of the school's Department of Preventive Medicine, the highest ranking preventive medicine department in the nation. He was a pioneering researcher, whose breakthroughs in understanding the causes and prevention of cancer brought hope to countless sufferers of this disease. With more than 250 scientific publications, he was considered a leading expert in hormone-related cancers, particularly of the breast, ovary, endometrium and prostate, and his work in this field garnered national and international acclaim. His research received the highest amount of funding from the National Institutes of Health of any faculty member at USC. At a special ceremony in February, he received the 2006 Distinguished Alumni Award for Achievement from the University of Iowa Alumni Association, its highest honor bestowed on the university's graduates. It is granted to those achieving significant accomplishments in professional life or for distinguished humane service to their community, state or nation. He continued to serve his alma mater by participating on the advisory boards for both the University of Iowa's College of Public Health and the Holden Comprehensive Cancer Center. He was devoted to his family and enjoyed coaching little league, sailing vacations, annual fishing trips to Mexico with his children, as well as having them accompany him on a number of work-related trips to other international destinations, such as Asia, Africa and Australia. On his yearly visits to Iowa, he also appreciated eating pork tenderloin sandwiches from the Cheri-Top drive-in, a business his father began in 1956. Survivors include his wife of 33 years; two sons, Jason, 26, and Jonathan, 23, and a daughter, Kalena, 20, all of the greater Los Angeles area; his mother, Betty Ross of Muscatine; and two brothers, Kenneth of Kailua-Kona, Hawaii and Troy of rural Muscatine. He was preceded in death by his father in 1963.
