Georgia K. Roberts, Ph.D., is a health scientist in the Program Operations Branch in the Division of the National Toxicology Program (NTP). Roberts assists the administration and monitoring of contracts for toxicology and carcinogenicity studies as well as analyses of existing scientific literature. She helps to design, conduct, interpret, and report the toxicology and carcinogenicity studies, and also leads NTP studies of crumb rubber, metals, industrial chemicals, herbal dietary supplements, and other potentially harmful exposures in the environment.

Roberts received a B.S. in biological sciences from Florida State University in 2009 and a Ph.D. in toxicology from the University of Florida Veterinary School in 2014. Before joining the Program Operations Branch, she was an NIEHS postdoctoral intramural research and training award (IRTA) fellow in the general toxicology and cancer group of the NTP Toxicology Branch.
