Research Toxicologist — Division of Genetic and Molecular Toxicology
Tao Chen, Ph.D., DABT
Dr. Chen received a Ph.D. in toxicology from the University of Arkansas for Medical Sciences, then worked as a postdoctoral scientist at Duke University. Dr. Chen joined FDA’s National Center for Toxicological Research (NCTR) as an FDA staff fellow in the Division of Genetic and Molecular Toxicology from 2000 to 2002 and became a research toxicologist in 2003. Dr. Chen has been a Diplomate of the American Board of Toxicology (DABT) since 1999.
Dr. Chen led a team to conduct research for development and validation of genotoxic methods and evolution of genotoxicity of FDA-related products. Dr. Chen’s early research mainly addressed the validation of rodent transgenic mutation systems and development of different methods for molecular characterization of chemical-induced mutations. He has investigated mutagenicity and fundamental mechanisms of mutagens associated with FDA regulations such as tamoxifen, retinyl palmitate, aristolochic acid, acrylamide, and drug impurities using different genotoxicity endpoints. Recent research has focused on the evaluation of genotoxicity assays for assessing nanomaterials, the development of new microRNA assays to supplement current genotoxicity battery, and the assessment of chemical-induced somatic and germline mutations using next generation sequencing methods.
