He is conducting epidemiological research on radiation carcinogenesis, using data on fallout at the United States' Nevada test site, on Japanese A-bomb survivors, and on medical irradiation. He is also developing statistical methods for genetic epidemiology, especially for studies of the relationship of gene-environment interactions to diabetes, breast cancer, and other cancers. He is author of two textbooks, Statistical Methods in Genetic Epidemiology (Oxford University Press, 2004) and Statistical Methods in Environmental Epidemiology (Oxford University Press, 2009). He was President of the International Genetic Epidemiology Society and served on President Clinton's Advisory Committee on Human Radiation Experiments.
