Dr. Tsuji is a board-certified toxicologist and a Fellow of the Academy of Toxicological Sciences, who specializes in risk assessment of chemical exposures. She has worked on projects in the United States and internationally for industry, trade associations, U.S. Environmental Protection Agency (EPA) and state agencies, the U.S. Department of Justice, the Australian EPA, municipalities, and private citizens. 

Dr. Tsuji's experience includes human health and environmental toxicology related to a wide variety of chemicals in the environment, industrial, commercial, and residential settings. She has designed and directed dietary and environmental exposure studies and community programs involving health education and biomonitoring for populations potentially exposed to metals in the environment, including soil, water, and air, and through food-chain exposures.

In addition to environmental exposures, she has also assessed exposure and health risks associated with substances in foods, medical devices, pharmaceuticals, and a variety of consumer products (e.g., cleaners, cosmetics, personal care products, paints and coatings, carpets, glues, wood preservatives, building materials, and children's products). Dr. Tsuji regularly serves on expert panels on toxicology and health risk issues, such as for the National Academies of Sciences, Engineering, and Medicine, National Research Council (including their Board on Environmental Studies and Toxicology), and federal and state agencies.
