About  |  Publications  |  Lab Members


Daniel R. Doerge was awarded a bachelor’s degree from Oregon State University and a Ph.D. degree from University of California, Davis. He was then an Assistant Associate Professor of Environmental Biochemistry at the University of Hawaii. Since 1992, he has been a Research Chemist in the Division of Biochemical Toxicology at NCTR.

Research Interests

Dr. Doerge’s areas of research specialization include chemical and biochemical mechanisms of toxicity, thyroid toxicology, toxicology of soy isoflavones, acrylamide, bisphenol A and inorganic arsenic. He also specializes in the applications of modern mass spectrometry that emphasize high-throughput determinations of pharmacokinetics and DNA adducts, as well as chemical risk assessment. A common strategy in this food-safety research is the integration of toxicokinetics and human biomonitoring with physiologically-based pharmacokinetic modeling to minimize uncertainty in the extrapolation of human risks from experimental animal toxicity testing. More than 250 peer-reviewed publications have resulted from this work. Dr. Doerge has served on chemical risk-assessment advisory committees for the European Food Safety Authority, World Health Organization, and U.S. Environmental Protection Agency. He has also served as editor-in-chief for Archives of Environmental Contamination and Toxicology
