Research Summary

Keith Shockley, Ph.D., is a bioinformatician for the National Toxicology Program (NTP) in the Biostatistics Branch at the National Institutes of Health’s National Institute of Environmental Health Sciences (NIH/NIEHS). Shockley came to the NIEHS in 2008 from The Jackson Laboratory in Bar Harbor, Maine, where he spent four years as a postdoctoral research associate studying statistical genetics and computational biology.

He is interested in using genetic and environmental data to improve toxicity testing. He assists members of the National Toxicology Program (NTP) to identify genes that control biological responses to environmental exposures, analyzes and interprets biological response data from high throughput screening assays, and scrutinizes gene expression data from large scale microarray studies. He has recently become interested in using chemoinformatics approaches to support chemical nominations and biomolecular screening, and in constructing genetic models to predict human toxicity.

Shockley received his B.S. in chemical engineering from New Mexico State University in 1998, and his M.S. and Ph.D. in chemical engineering from North Carolina State University in 2000 and 2004, respectively.
