Dr. Dorgan is an epidemiologist with particular expertise in molecular and nutritional epidemiology. She has a Ph.D. in Epidemiology from the Johns Hopkins School of Hygiene and Public Health, a M.P.H. in Nutrition from the University of North Carolina School of Public Health, and a B.S. in Biology from Cornell University. She did her post-doctoral training in Cancer Prevention and Control at the National Cancer Institute.
After completing her M.P.H. in Nutrition, Dr. Dorgan worked on national nutrition policy at the U.S. Department of Agriculture. She subsequently earned her Ph.D. in Epidemiology, and since that time has conducted epidemiologic research at the Institute of Nutrition for Central America and Panama, Maryland Medical Research Institute, the National Cancer Institute, and Fox Chase Cancer Center.
Dr. Dorgan currently is a tenured Professor in the Division of Cancer Epidemiology, Department of Epidemiology and Public Health at the University of Maryland Baltimore School of Medicine. She is an adjunct scholar in the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania and holds an adjunct faculty appointment at Drexel University.
Dr. Dorgan’s research focuses primarily on identifying hormonal determinants of cancer, particularly breast cancer, and hormonal mechanisms by which environmental and behavioral exposures, as well as genetics, affect cancer risk. While at the National Cancer Institute (NCI) she was the Principal Investigator of the Columbia, MO Serum Bank, which is a long-standing prospective cohort study of women. Since leaving NCI, Dr. Dorgan continues to actively participate in research based on this cohort to identify hormonal, environmental and nutritional influences on cancer risk. Mullerian inhibiting substance (MIS) is a serum marker of ovarian function that Dr. Dorgan recently found to be strongly positively related to breast cancer risk. Genetics is a major determinant of circulating MIS levels, and currently Dr. Dorgan and colleagues are evaluating associations of genes that encode MIS and its receptors with breast cancer in a large case-control study. Considerable data from animal models and in vitro studies also support a role for MIS in ovarian and endometrial cancers, and Dr. Dorgan also currently is prospectively evaluating associations of MIS with these reproductive cancers in 9 cohorts from around the world.
Dr. Dorgan also conducts research on early life exposures and adult chronic disease risk. In a recently completed follow-up of female participants of the Dietary Intervention Study in Children to evaluate the longer-term effects of a diet intervention to lower fat intake during childhood and adolescence on biomarkers associated with breast cancer risk, the intervention group had lower fasting plasma glucose, lower blood pressure and lower large very-low-density lipoprotein particles, an early marker of insulin resistance, compared to the usual care control group. Interestingly, insulin-related biomarkers did not differ by treatment group during childhood and adolescence, and Dr. Dorgan and her colleagues speculate that the emergence of these differences as the cohort ages could be due to epigenetic changes in response to dietary differences during youth that become apparent with age-related adverse changes in metabolic parameters. Dr. Dorgan and colleagues are continuing to conduct analyses and anticipate that many novel findings will come from this unique resource. In ongoing studies they are evaluating associations of adolescent adiposity and serum hormones with breast density in young adulthood.
