Diane L. Spencer, M.S., is a Health Scientist in the Office for Research, where she serves as a scientific, technical, and administrative resource. Before joining this group in 2016, she worked as a Biologist/Health Scientist in the Office of Report on Carcinogens for seven years and in the NTP Center for the Evaluation of Risks to Human Reproduction (CERHR) for five years. Prior to Spencer's work at CERHR, she worked for six months in the NTP Office of Liaison, Policy and Review, helping to coordinate scientific workshops and exhibitions for NTP. Spencer has been employed at NIEHS since 1984, initially as a laboratory technician in the Laboratory of Environmental Carcinogenesis and Mutagenesis, and later as a researcher and laboratory manager in the Laboratory of Computational Biology and Risk Analysis.

Research interests in the laboratory included projects assessing human risk associated with dioxin (TCDD) exposure. She developed an assay using human peripheral blood lymphocytes to measure constitutive and TCDD-induced expression of CYP1B1 using quantitative reverse transcriptase-polymerase chain reaction (RT-PCR). Earlier laboratory research involved using cultured mammalian cell lines and molecular biology techniques to investigate mechanisms of mutagenesis, with specific emphasis on mutation rates and "epigenetic" mechanisms of mutation induction.

A charter (1982) member of the Genetics and Environmental Mutagen Society, Spencer has served as Secretary, Treasurer, President-Elect, and President, and continues to be an active member of the Society.

Spencer, a native of Canada, earned a B.A. in biology from Rollins College in Winter Park, Florida and an M.S. in biology from the University of Miami in Coral Gables, Florida.
