The twenty-eight faculty of our interdepartmental program come from sixteen different departments in the School of Medicine, the School of Public Health and the College of Letters and Science at UCLA. Members of our faculty also participate in the activities of the UCLA Jonsson Comprehensive Cancer Center, and the newly established California Nanosystems Institute. A major advantage of UCLA is that the above entities are all in close proximity to one another on campus, providing our students with a wide range of educational and research opportunities. Our students also participate in many of the activities of the other biomedical science doctoral programs at UCLA. Areas of particular strength in our program include chemical carcinogenesis, repair of DNA damage, air pollution toxicology, nanotoxicology, and the environmental causation of Parkinson's disease. The program is supported by a training grant from the National Institute of Environmental Health Sciences (NIEHS). Our program is now in its eleventh year. Students from our first seven years (2000-2007) have all graduated.
