Stephanie L. Smith-Roe, Ph.D., is a genetic toxicologist in the Genetic Toxicology Group within the Biomolecular Screening Branch (BSB) of the National Toxicology Program (NTP).

Smith-Roe designs experiments to evaluate the genotoxic potential of chemicals, and provides genetic toxicology test data review and evaluation for inclusion in the NTP Technical Reports. She assists with management of the NTP's genetic toxicology testing contract, while also contributing to assay selection, design, and analysis for the NTP initiative for High Throughput Screening (Tox21 Collaboration).

After obtaining a B.S. in Zoology and Psychology (specializing in biochemistry and neuroscience) from the University of Wisconsin-Madison, Smith-Roe received her Ph.D. in Environmental and Molecular Toxicology from Oregon State University. Upon completion of her graduate work, she held a postdoctoral fellowship in the Curriculum in Toxicology at the University of North Carolina at Chapel Hill. She has conducted research in the areas of carcinogenesis, DNA replication, DNA repair, DNA damage signaling, checkpoint signaling, and chromatin remodeling using mouse models and molecular approaches.

Smith-Roe is active in national and local societies dedicated to research and issues related to understanding the causes and consequences of genomic instability. She is a member of the Environmental Mutagenesis and Genomics Society (EMGS), where she has co-chaired several symposia, served as a Councilor, held an appointment as a Councilor Liaison to the Executive Board, and co-chaired or served on numerous committees and task forces. Presently, she is the Chair for the EMGS New Technologies Special Interest Group. She is also a Past President of the Genetics and Environmental Mutagenesis Society (GEMS), headquartered in the Research Triangle Park, NC.

Currently, Smith-Roe is an Editorial Board member of Mutation Research - Genetic Toxicology and Environmental Mutagenesis. She also recently contributed as a Working Group member to the International Agency for Research on Cancer (IARC) Monographs on the Evaluation of Carcinogenic Risks to Humans, Volume 121.
