PFAS, Heavy Metals & Contamination Expert Witness

I provide expert witness services for litigation involving PFAS (per- and polyfluoroalkyl substances), heavy metals, microbial contamination, and other chemical or physical adulterants in cosmetic and OTC personal care products. These matters require an expert who can bridge formulation chemistry, analytical testing methodology, regulatory standards, and manufacturing practice — a combination that defines my professional background.

PFAS and heavy metal contamination in cosmetics has become one of the most active litigation areas in the personal care industry, driven by third-party testing studies, consumer class actions, and increasing regulatory scrutiny. My chemistry training and industry experience allow me to evaluate the source of contamination, assess the adequacy of manufacturer testing programs, and analyze causation and consumer exposure in a litigation context.
