Much of the work carried out by DTT is in support of the National Toxicology Program (NTP), an interagency partnership of the Food and Drug Administration, National Institute for Occupational Safety and Health, and NIEHS.

Report on Carcinogens

Ruth Lunn, Dr.P.H., is the director of the Office of the Report on Carcinogens. The RoC is a congressionally-mandated document, prepared on behalf of the Secretary of the Department of Health and Human Services that lists and discusses substances that cause or are anticipated to cause cancer. Preparation of the RoC follows a formal, multi-step process that includes scientific review and opportunity for public comment. Lunn provides scientific expertise needed for the overall evaluation of substances for their potential to cause cancer in humans and is responsible for preparing the final draft of the RoC. She has worked with the RoC since 2000, initially as a staff scientist, and more recently as director. During this time, she has contributed to the preparation of numerous scientific background documents that are used in the scientific review process.

Prior to joining the RoC, Lunn's more recent research interests were molecular epidemiology studies evaluating carcinogenicity and genetic susceptibility. She completed postdoctoral work at the National Institute of Environmental Health Sciences in Research Triangle Park, North Carolina, and received a Dr.P.H. in environmental health sciences from Columbia University, New York, New York. She also earned a M.S. in microbiology and immunology and a Master of Clinical Microbiology (M.C.M.) from Hahnemann University, Philadelphia, Pennsylvania.
