Area of interest
I am interested in occupational and environmental epidemiology, with a special emphasis on occupational and environmental carcinogens. Much of my epidemiological research focuses on radiation carcinogenesis, using data on workers at the United States' nuclear weapons production facilities and, recently, on Japanese A-bomb survivors. Other current work considers established or suspected carcinogens, including asbestos, benzene, and beryllium. This work focuses on the development of statistical methods for cancer epidemiology, particularly methods to characterize exposure-time-response associations and methods to minimize the impact of exposure measurement error in occupational and environmental studies. Current work on methodological developments for occupational cancer research, supported via an investigator initiated research project grant (RO1) from the National Cancer Institute, and recent work on mortality among asbestos textile workers (supported via an RO1 from the National Institute for Occupational Safety and Health), involves collaboration with colleagues in the Department. My research on radiation epidemiology (also supported via an RO1 from the National Institute for Occupational Safety and Health) has involved collaboration with colleagues in the Departments of Epidemiology and Environmental Sciences and Engineering.
The second line of research involves theoretical models of carcinogenesis and their application to analyses of exposure-time-response associations. This work, currently supported via a Career Development Award (KO1) from the National Institute for Occupational Safety and Health, has opened up opportunities for a new set of collaborators within the University and NIOSH. One paper on the application of multistage cancer models to analysis of benzene-leukemia associations has just been published, while an example of the application of multistage cancer models to analyses of radiation-induced cancer was presented at the 18th Conference of the International Society for Environmental Epidemiology (ISEE), Paris, 2006.
In summary, I see my career continuing to build upon my interest and expertise in the area of occupational cancer epidemiology. I see a clear need for this line of research and substantial interest in it from federal agencies involved in cancer research, occupational health and safety, and environmental protection.
