Cynthia Rider, Ph.D., joined the National Toxicology Program (NTP) as a toxicologist in 2010. As a study scientist in the Toxicology Branch, she designs and evaluates results from toxicological studies of chemicals selected for investigation by the NTP. She is particularly interested in developing methods for assessing mixture toxicity based on data from individual chemicals.
Rider received her B.S. from Tulane University, New Orleans, LA in Environmental Studies and Biology and her Ph.D. from North Carolina State University, Raleigh, NC in Environmental Toxicology. She completed post doctoral training in the Reproductive Toxicology Branch of the National Health and Environmental Effects Research Laboratory, U. S. Environmental Protection Agency and the Nicholas School of the Environment at Duke University.
