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

Smith-Roe designs experiments to evaluate the genotoxic potential of chemicals and reviews and evaluates results for inclusion in the NTP technical reports. She assists with management of the NTP’s genetic toxicology testing contract. Smith-Roe also contributes to assay selection, design, and analysis for the NTP initiative for High Throughput Screening (Tox21 Collaboration).

Smith-Roe acquired training in genetic toxicology and in molecular and cellular biology in the pursuit of understanding the causes and consequences of genomic instability. She has conducted research in the areas of DNA replication, DNA repair, DNA damage signaling, checkpoint signaling, and chromatin remodeling using mouse models and cell culture approaches. Smith-Roe also has a background in neurobehavioral science (learning, memory, and stress).

Smith-Roe is active in national and local societies dedicated to research and issues surrounding genomic health. Smith-Roe is a member of the Environmental Mutagenesis and Genomics Society (EMGS). She served as a Councilor and held an appointment as a Councilor Liaison to the Executive Board. Smith-Roe is a Past President of the Genetics and Environmental Mutagenesis Society (GEMS), headquartered in the RTP. She previously served GEMS as a Councilor on the Board of Directors.

Smith-Roe serves as an editorial board member of Mutation Research - Genetic Toxicology and Environmental Mutagenesis.

Smith-Roe obtained a B.S. in Zoology and Psychology from the University of Wisconsin-Madison and received her Ph.D. in Environmental and Molecular Toxicology from Oregon State University. Upon completion of her graduate work, Smith-Roe obtained a postdoctoral fellowship at the University of North Carolina at Chapel Hill.
