Joyce S. Tsuji
oyce Tsuji, Ph.D., DABT, Fellow A.T.S., is a Principal with Exponent’s Health Sciences practice and a board-certified toxicologist and Fellow of the Academy of Toxicological Sciences. Her particular areas of interest include exposure assessment and toxicology of a variety of chemicals released to the environment, in consumer products, or in food. She has directed several projects to evaluate applications of nanotechnology and to assess potential risks of specific nano-scale materials used in consumer products, including investigations of interactions between the material properties of the product and the nanoscale ingredients that might affect exposure to free nanomaterials. Dr. Tsuji has organized, chaired, and presented at scientific symposia and workshops on various topics related to health and environmental risks of nanomaterials, and has published on the use of toxicology and exposure data in assessing the risks of nanomaterial applications.
