Ms. Claire Hamaji is a dedicated human health risk assessor and regulatory toxicologist with 11 years of experience evaluating exposures to chemicals among consumers, workers, and the general public. As a scientist, she seeks to understand the nature and extent of human health risks presented by chemicals used in industry and commerce in order to inform better environmental policy from the local to national level.
Ms. Hamaji’s professional specialties include regulatory toxicology, quantitative human health risk assessment methods, and dermal exposure assessment. Over her career, she has amassed extensive experience managing and providing support on cases involving unique chemical exposures among populations that include industrial workers, consumers, children, and firefighters. Further, she has broad experience conducting human health risk assessments for contaminated sites, including addressing the regulatory and technical factors that make each site a unique challenge. Ms. Hamaji has investigated exposures to a wide variety of chemicals, including heavy metals, brominated flame retardants, PCBs, per- and polyfluoroalkyl substances (PFAS), perchloroethene (PCE), and wildfire smoke. Her other scientific interests include science communication and advocating for gender equity within science.
