Duncan Thomas, Ph.D.

Photograph of Duncan Thomas Duncan Thomas, Ph.D., is a Professor of Preventive Medicine, the Director of the Biostatistics Division, and the Verna R. Richter Chair in Cancer Research. He is the Co-Leader of the Cancer Epidemiology Program

Dr. Thomas received his B.A. in Mathematics from Haverford College, Haverford, Pennsylvania in 1967. He obtained his M.S. in Astronomy/Mathematics from Stanford University, Stanford, California in 1969. He received his doctorate in Epidemiology/Biostatistics from McGill University, Montreal, Quebec, Canada in 1976.

His primary research interest has been in the development of statistical methods for environmental and genetic epidemiology, with numerous collaborations in both areas. On the environmental side, he has been particularly active in radiation carcinogenesis and air pollution health effects research, notably as one of the senior investigators on the Southern California Children’s Health Study and served on President Clinton’s Advisory Committee on Human Radiation Experiments. On the genetic side, he is a Co-Investigator in the NCI’s Colon Cancer Family Registry, the Genetic Analysis Workshop, the ENDGAME Consortium to develop methods for genome-wide association studies, and past President of the International Genetic Epidemiology Society.

Dr. Thomas has numerous publications, including the textbooks Statistical Methods in Genetic Epidemiology (Oxford University Press, 2004) and Statistical Methods in Environmental Epidemiology (Oxford University Press, 2009). These three broad areas of interest make him uniquely qualified to address methodological challenges in studying gene-environment interactions.
