    Dr. Amy Williams is a board-certified toxicologist. She has over 20 years of experience in the evaluation of crop protection compounds, pharmaceuticals (including both small molecules and biologics), industrial chemicals, chemicals in consumer products and foods, and power frequency and radiofrequency exposures for potential adverse effects on human health. 

    Dr. Williams specializes in developmental and reproductive toxicology, endocrine disruption, carcinogenicity mode-of-action assessments, and general toxicology related to exposure to chemical substances and physical agents.

    Dr. Williams has worked on projects related to understanding the human relevance of developmental toxicity study findings for pesticides and biocides; assessed the potential for endocrine-disrupting effects; evaluated mechanistic data to address developmental and carcinogenicity modes-of-action; assisted in the design and monitoring of studies to assess the developmental, reproductive and endocrine effects of test agents; conducted consumer product chemical exposure assessments; and assisted in the interpretation of experimental study results for assessing the health effects of electromagnetic and radiofrequency exposures. Dr. Williams also has considerable experience in communicating health risks to the public.

    Prior to joining Exponent, Dr. Williams was a Principal Scientist at Noblis/Mitretek Systems, where she provided toxicological analysis and support to both government and commercial clients related to chemicals of concern for environmental clean-up, drug substances and excipients, veterinary pharmaceuticals, and crop-protection compounds. Additionally, Dr. Williams has lectured on principles of basic toxicology and worked on programs related to chemical and biological warfare agents for the Department of Defense and the development of predictive toxicity measures for chemicals of concern for the Department of Homeland Security.

    Dr. Williams also held the position of Scientific Program Manager at the Health and Environmental Sciences Institute (HESI), where she directed a diverse set of projects related to the development and application of toxicology data in health safety risk assessments. She managed expert committees examining alternatives to carcinogenicity testing, immunotoxicology, the evaluation of epidemiology studies, and the development of biomarkers for safety assessment. In this position, her responsibilities included research project development and coordination, technical writing, and the organization of conferences and meetings.
