About  |  Publications  |  Lab Members


 Dr. Chen received his Ph.D. degree in toxicology from the University of Arkansas for Medical Sciences in 1997. After graduation, he worked as a postdoctoral scientist at Duke University until 2000. Dr. Chen was an FDA staff fellow in the Division of Genetic and Molecular Toxicology from 2000 to 2002 and has been a research toxicologist in 2003. Dr. Chen has been a Diplomate of the American Board of Toxicology since 1999.

Research Interests

Dr. Chen leads a team that conducts research to develop and validate genotoxic methods and to better understand the genotoxicity of FDA-related products. Dr. Chen’s early research mainly addressed the validation of rodent transgenic-mutation systems and the development of different methods for the 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 other drug impurities using different genotoxicity endpoints. He has recently focused his research on the evaluation of genotoxicity assays for assessing nanomaterials. He also looks to the development of new microRNA assays to supplement current genotoxicity battery. Finally, Dr. Chen is interested in the assessment of chemical-induced somatic and germline mutations using next-generation sequencing methods.
