Dr. Claudia Miller co-authored a landmark report for the state of New Jersey on chemical susceptibility, for which the state received the American Association for World Health’s Macedo Award, and a professionally acclaimed book, Chemical Exposures: Low Levels and High Stakes (2nd edition, John Wiley and Sons, Inc., New York, 1998). She has authored or co-authored numerous book chapters and peer-reviewed publications on the health effects of low-level chemical exposures.
Her federal appointments include: the National Advisory Committee on Occupational Safety and Health, the Department of Veterans Affairs Persian Gulf Expert Scientific Committee, and the National Toxicology Program Board of Scientific Counselors. She has served as consultant to the chief-of-staff of the Houston VA for its Persian Gulf Regional Referral Center, and as an advisor to the Texas Department of Health, the Environmental Protection Agency, the Agency for Toxic Substances and Disease Registry, and the Canadian, German, Japanese, and Swedish governments. During her sabbatical year, she served as special consultant to the Deputy Director of the National Institute of Environmental Health Sciences (NIEHS/NIH). She has organized and chaired two NIH meetings on chemical intolerance, one in Tokyo that focused on the need for and use of environmentally controlled hospital units for research, the other on Toxicant-Induced Loss of Tolerance, the disease mechanism she first described in 1996.
Dr. Miller is professor emeritus at the UT Health San Antonio and visiting senior scientist at Harvard’s T.H. Chan School of Public Health. She was recruited by the Marilyn B. Hoffman Foundation in 2015 to be its environmental scientific consultant. Dr. Miller and Ms. Hoffman, who died in 2013, had known each other for several years because of their mutual scientific interests. Ms. Hoffman named Dr. Miller and TILT, or Toxicant Induced Loss of Tolerance, the term she preferred for related illnesses, in her bequest to the foundation.
