Christopher Simpson is Professor and Assistant Chair for Research and Faculty Engagement in the UW Department of Environmental & Occupational Health Sciences. He also directs the Northwest Center for Occupational Health and Safety. Dr. Simpson is the Deputy Director of the Pacific Northwest Agricultural Safety and Health (PNASH) Center.
His research interests involve the application of analytical chemistry to the development of techniques for assessment of exposure to toxic chemicals, and the subsequent application of those techniques to investigate occupational and environmental exposures. He is particularly interested in the development of analytical methodology to measure xenobiotics and their metabolites or transformation products in biological samples (biomarkers). In support of these efforts, he conducts studies to develop sampling and analysis methods for environmental samples to provide accurate external exposure measures to validate the biomarkers.
