Nigel Walker, Ph.D., D.A.B.T., is a staff scientist in the Systems Toxicology Branch, in the Division of Translational Toxicology (DTT) at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health (NIH).

Walker leads the federal interagency Office of National Toxicology Program (NTP) Scientific Operations and Coordination (ONSOC) and in that role provides senior level scientific leadership and direction for the planning, implementation, management, and coordination of research activities of theNational Toxicology Program (NTP). The NTP is a Federal interagency program that generates, interprets, and shares toxicological information about potentially hazardous substances in our environment to provide the scientific basis for programs, activities, and policies that promote health or lead to the prevention of disease.

Walker has been at the NIEHS for over 25 years and during this time has led numerous initiatives understanding the potential toxicity and carcinogenicity of compounds under investigation by NTP including nanoscale materials, dioxin-like compounds, persistent organic pollutants, environmental/occupational mixtures, endocrine disrupting compounds, and botanical dietary supplements.

Walker has co-authored over 200publications, including over 100peer-reviewed technical reports on the toxicity and carcinogenicity of compounds studied by NTP.

He received his B.Sc. in Biochemistry from the University of Bath in the U.K. and his Ph.D. in Biochemistry from the University of Liverpool, U.K. and has been board certified as a toxicologist by the American Board of Toxicology since 2007.
