June K. Dunnick, Ph.D., is a toxicologist in the Toxicology Branch, which promotes, designs and administers research programs to understand how environmental exposures affect the public’s health. Research is focused on identifying and evaluating the beneficial and harmful effects of environmental chemicals, drugs, metals and other chemicals of concern so that strategies can be developed to prevent exposures to harmful agents or to develop disease prevention strategies particularly for cancer, reproductive disease, and infectious diseases. This involves the design, analysis, and interpretation of experimental studies to identify biological effects, and extrapolation of results to man through the use metabolism/pharmacokinetic studies and mechanistic studies. Her responsibilities include serving as senior scientist for toxicologic and carcinogenesis studies and identifying new initiatives for the development of a better understanding of environmental disease, through the integration, extrapolation and analysis of data from a broad range of experimental studies. She also serves as a focus, representative and spokesperson for the Institute when reporting the findings from toxicology and carcinogenesis research studies.

Dr. Dunnick received a B.S. from Cornell University, Ithaca, New York , a Ph.D. from Cornell University Medical College, New York, New York, and a MBA from Kenan-Flagler Business School, UNC, Chapel Hill, NC. She completed postdoctoral work in the Department of Biochemistry, University of Rochester Medical School, Rochester, New York. Dr. Dunnick is a Diplomat of the American Board of Toxicology.
