Xiaohua Gao, M.D., Ph.D. is a Research Fellow in the National Toxicology Program Laboratory of the Division of the National Toxicology Program at the National Institute of Environmental Health Sciences. As a trainee under the supervision of Dr. Darlene Dixon in the Molecular Pathogenesis Group, Gao’s work focuses on the molecular basis of disease and understanding the pathogenesis of toxicant-induced changes in female reproductive tract tissues and in vitro assays in human cells, to assess the molecular mechanisms and signaling pathways of environmental substances that are of importance to the NTP testing program.

Gao received her M.D. and Ph.D. in Toxicology from Nanjing Medical University in Nanjing, China. Her doctoral research focused on the effects of pesticides and other endocrine disrupting chemicals (EDCs) on calmodulin signaling and T-type calcium channels of the reproductive tract using animal models and in vitro germ cells. Gao joined NIEHS as a visiting fellow in 2008.
