Careers in Chemical Regulation & Food Safety

"In the Center for Chemical Regulation & Food Safety, we have the opportunity to work on a wide variety of challenging projects that require the integration of technical and regulatory expertise to successfully address our clients' global business needs."

-- Carrie L. Daniels

Senior Managing Regulatory Consultant

The Center for Chemical Regulation & Food Safety is part of Exponent's Health Sciences Group. Our staff includes scientists, nutritionists, and regulatory consultants in both the U.S. and Europe who have expertise in regulatory and technical support for chemicals (pesticide and non-pesticide), food safety and nutrition, human health exposure and risk assessment, environmental modeling and risk assessment, and REACH implementation. Many of our consultants have had previous experience working for the US EPA, US FDA, UK PSD, and other government agencies, or have had careers within academia or the chemical and food industries. We hold advanced degrees in Chemistry, Biology, Environmental Sciences, Toxicology, Public Health, Epidemiology, Nutrition and other related fields. Our consultants continue to publish in peer-reviewed journals and are actively involved in scientific associations and international committees.
