NIH recently awarded scientific tenure to Amy Berrington de González, D.Phil., of the Radiation Epidemiology Branch, and Rachael Stolzenberg-Solomon, Ph.D., M.P.H., R.D., of the Nutritional Epidemiology Branch.
Dr. Berrington de González's research is focused primarily on the use of epidemiological data to quantify the cancer risks related to medical radiation exposures, including both low-dose exposures from diagnostic tools, such as computed tomography scans, and high-dose exposures from radiotherapy. She is interested particularly in the cancer risks from emerging technologies, such as intensity-modulated radiotherapy and proton therapy. Before joining DCEG, Dr. Berrington de González received her doctoral degree in cancer epidemiology from the University of Oxford in the United Kingdom, and she was a faculty member at both Oxford and the Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland.
Dr. Stolzenberg-Solomon has focused much of her research on understanding the etiology of pancreatic cancer. She has examined dietary, other lifestyle, and genetic factors as well as infectious agents that may help uncover mechanisms of carcinogenesis. Whenever possible, she has utilized biomarkers in cohort and intervention studies of cancer etiology and prevention, paying special attention to aspects of one-carbon metabolism (a biochemical pathway in which folate plays an essential role) in the etiology of gastrointestinal, renal cell, and colorectal cancers. After completing her education and training in nutrition at the University of California, Davis, and at Vanderbilt University in Nashville, Tennessee, Dr. Stolzenberg-Solomon worked for a number of years as a registered dietitian in clinical care and research. She received her M.P.H. in nutrition and epidemiology as well as her Ph.D. in epidemiology from the Johns Hopkins Bloomberg School of Public Health.
