Engineered nanomaterials offer many potential benefits to society, but there are growing concerns about their possible impacts on health. To evaluate and minimize the risk of engineered nanomaterial exposure, I conduct field monitoring and laboratory experiments of dustiness tests as well as developing exposure assessment methods.
