Background

Dr. Qiangen Wu received a B.S. in preventive medicine from Central South University Xiangya School of Medicine in 2002. He earned a Ph.D. in occupational and environmental health from Fudan University School of Public Health in 2007 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) from 2008 to 2011, where he investigated the induction of DNA damage and repair by the anti-HIV drug zidovudine. Dr. Wu continued his carcinogenesis research in the Department of Environmental Health at Indiana University Bloomington from 2011 to 2015, 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 (ROS) and their biological effects using high performance liquid chromatography-tandem mass spectrometry (LC/MS/MS).  

In 2015, Dr. Wu was recruited by the Analytical Chemistry Support Group at NCTR as an FDA Visiting Scientist/Staff Fellow, where he worked on multiple projects funded by NCTR, the Center for Tobacco Products (CTP), and the National Toxicology Program (NTP) using mass spectrometry. In October 2019, Dr. Wu became a member of the Inhalation 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.

Research Interests

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 leads 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 the exposure to carcinogens. Currently, Dr. Wu is working on the effects of vehicle on the pharmacokinetics profile of nicotine in Sprague-Dawley rats following nose-only inhalation exposure.
