Michael K. Peterson, M.E.M., DABT Principal [email protected]
Areas of Expertise Mr. Peterson is a Principal at Gradient more than 20 years of experience specializing in human health risk assessment • Human Health Risk Assessment of cancer and non-cancer endpoints, critical analysis of • Product Safety Evaluation human and animal toxicology and epidemiology studies, • Applied Toxicology and multimedia assessment of exposure to chemicals. He has applied these skills primarily in the areas of product • Toxic Tort Litigation Support safety, occupational safety and health, and risk assessment. • Pesticide Toxicology He has extensive experience evaluating the toxicity of asbestos and other fibers. He also has experience Education evaluating exposures to chemicals in a variety of different M.E.M., Environmental Toxicology and Risk consumer products, and developing toxicity guidelines for those chemicals. Assessment, Duke University Many of his projects have involved preparing risk communication materials to effectively convey chemical exposure risks in appropriate context for a variety B.S., Chemistry and Environmental Science, of stakeholders. He is an appointed member of the Washington Governor's Bradley University Industrial Safety and Health Advisory Board, the President of the Occupational and Public Health Specialty Section of the Society of Toxicology, and the Diplomate of the American Board of Toxicology Chairperson of the Washington Agriculture Safety Day Committee. While earning a Masters of Environmental Management degree at Duke University, Mr. Peterson researched the oral bioavailability of polycyclic aromatic Selected Presentations hydrocarbons from soil. and Publications Peterson, MK; Mohar, I; Lam, T; Cook, TJ; Lynch, HN; Engel, AM. 2019.
