I have 15 years of experience in the field of human health risk assessment, with specific knowledge in the areas of consumer products, personal care products and cosmetics. I have published on such topics as human health risk assessment procedures, personal care products, and drinking water safety. I am the owner of a toxicology consulting firm in the United States, and work for both the public sector (e.g., US EPA) and private sector. I am equally trained in toxicology and human health risk assessment.
