Qiangen Wu, Ph.D., DABT
Dr. Qiangen Wu received a B.S. degree in preventive medicine from Central South University Xiangya School of Medicine. He earned a Ph.D. in occupational and environmental health from Fudan University School of Public Health and worked as a lecturer for a year in the same university.
Dr. Wu started his postdoctoral training at the Division of Biochemical Toxicology (DBT) at FDA’s National Center for Toxicological Research (NCTR), where he investigated the induction of DNA damage and repair by the anti-HIV drug zidovudine. Dr. Wu continued his carcinogenesis research at the Department of Environmental Health at Indiana University Bloomington, where he primarily investigated the mechanisms underlying the development of pancreatic cancer by perfluorooctanoic acid in mice. He expanded his research in the Oxidative Stress Environmental Analysis Core Laboratory by studying reactive oxygen species and their biological effects using high performance liquid chromatography-tandem mass spectrometry.
In 2015, Dr. Wu was recruited by the Analytical Chemistry Support Group at DBT/NCTR as an FDA visiting scientist/staff fellow, where he worked on multiple projects funded by NCTR, the Center for Tobacco Products, and the National Toxicology Program using mass spectrometry. In October 2019, Dr. Wu became a member of the Inhalation Toxicology Core group to conduct tobacco toxicological research. Dr. Wu was certified as a toxicologist by the American Board of Toxicology in 2013 and recertified in 2018. His research efforts have resulted in more than 50 papers published in peer-reviewed journals.
Dr. Wu’s research mainly focuses on the metabolic activity pathways leading to the toxicity and tumorgenicity of FDA-regulated products—especially tobacco products. He investigates the metabolism of toxic chemicals that lead to cytotoxicity, genotoxicity, and carcinogenicity. Using tandem mass spectrometry and high-resolution mass spectrometry, Dr. Wu investigates the formation of the exogenous and endogenous DNA adducts and elucidates the mechanism of tumorgenicity mediated by free radical or nucleophilic metabolites after exposure to carcinogens. Currently, Dr. Wu is working on the effects of vehicles on the pharmacokinetics profile of nicotine in rats following nose-only inhalation exposure.
Using mass spectrometry, Dr. Wu is also evaluating the pharmacokinetics of cannabidiol and its major metabolites in rats upon dermal exposure and in pregnant rats and their pups after oral cannabidiol administration.
