Chad Blystone, Ph.D., D.A.B.T., is a toxicologist in the Toxicology Branch of the National Toxicology Program (NTP) at the National Institute of Environmental Health Sciences. He serves as a study scientist for chemicals selected for toxicity and carcinogenicity evaluation by the NTP. Currently he is the lead on studies evaluating chemicals within the classes of parabens, phthalates, ethylene glycol ethers and perfluoroalkyl acids. These studies include in vitro and in vivo evaluation of toxicity, toxicokinetics, absorption, disposition, metabolism and excretion of the chemical. He has a particular interest in elucidating chemical toxicity to reproduction and development, developmental basis of disease, and the adverse effects from chemical mixtures.

Blystone received a B.S. in zoology from Auburn University, Auburn, Alabama, an M.S. in zoology from Miami University, Oxford, Ohio, and a Ph.D. in toxicology from North Carolina State University, Raleigh, North Carolina. He completed postdoctoral work at the National Health and Environmental Effects Research Laboratory within the U. S. Environmental Protection Agency, and at the NTP at the NIEHS. Blystone joined the NTP in 2009.
