Background

Jia-Long Fang received a bachelor’s degree in public health in 1985 from Shanghai Medical University, one of the most prestigious medical universities in China, and a master’s degree in toxicology in 1990 from Chinese Academy of Preventive Medicine, one of the top institutes for health research in China. In 1997, Dr. Fang received a Ph.D. in Molecular Epidemiology from the renowned Karolinska Institute in Stockholm, Sweden. He joined NCTR as an ORISE Postdoctoral Fellow in 1997 and rejoined NCTR as a Staff Fellow in 2004. He was converted to a Research Biologist in 2010.

Research Interests

Dr. Fang has over twenty years of research experience in biochemical carcinogenesis and toxicology. He has designed, developed, and executed in vitro and in vivo research studies that address the biological mechanisms underlying the toxicities of drugs and chemicals. Throughout his career at NCTR, Dr. Fang’s research has been focused on the biological mechanisms of action underlying the toxicity of chemicals regulated by ─ or of interest to ─ FDA. Some of these chemicals are ethanol, urethane, tolvaptan, and antiretroviral drugs, including zidovudine, lamivudine, and nevirapine. More recently, Dr. Fang has been leading a research team to investigate the toxicities of topically applied triclosan.
