Nicole C. Kleinstreuer, Ph.D., began her role as Deputy Director of the NTP Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM) in 2016. NICEATM conducts data analyses, workshops, independent validation studies, and other activities to assess new, revised, and alternative test methods and strategies and provides support for the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM). Kleinstreuer leads NICEATM’s computational toxicology work, helps provide oversight of the NICEATM support contract and assists Warren Casey, Ph.D., in achieving the ICCVAM goals as articulated in the ICCVAM Authorization Act of 2000. She also holds a secondary appointment in the NIEHS Biostatistics and Computational Biology Branch.

Prior to joining NTP, Kleinstreuer worked for Integrated Laboratory Systems, Inc., as a senior staff computational toxicologist and director of the ILS computational toxicology group supporting NICEATM.

Kleinstreuer received her Ph.D. in bioengineering from the University of Canterbury in Christchurch, New Zealand, and B.S. degrees in mathematics and biomedical engineering from the University of North Carolina at Chapel Hill (UNC-CH). Prior to joining ILS, she completed postdoctoral training at the EPA National Center for Computational Toxicology. Kleinstreuer also maintains an adjunct faculty appointment at the Eshelman School of Pharmacy at UNC-CH.

Kleinstreuer’s research focuses on mathematical and computational modeling of biological systems and their susceptibility to perturbations that result in adverse health outcomes. She was a key contributor to a strategy that combines in vitro high throughput assay data with computational models for measuring estrogen receptor bioactivity. This strategy has been accepted by the U.S. Environmental Protection Agency (EPA) as an alternative to three existing Tier 1 tests in the Endocrine Disruptor Screening Program. She leads current efforts to identify alternative testing strategies to screen for androgen receptor bioactivity, as well as international efforts to facilitate regulatory acceptance of skin sensitization test methods that do not use animals. Kleinstreuer also worked closely with the Halifax Project and on associated NIEHS initiatives to identify low-dose chemical effects on cancer hallmark pathways.

Kleinstreuer has won numerous awards including the 2016 F. Clarke Fraser New Investigator Award from the Teratology Society, the 2015 Edward Carney Award for Predictive Toxicology from the American Society for Cellular and Computational Toxicology, an NIEHS group merit award, the Burroughs Wellcome Fund Innovation in Regulatory Science Award, and the B.H. Neumann Prize from the Australian Mathematical Society.
