Sa Liu is an exposure scientist specializing in occupational and environmental exposure assessment. Her research focuses on the development and the implementation of comprehensive assessment methods to understand human exposures to chemical contaminants and their association with adverse health effects among workers and the general population. The overarching question of her research is how scientific data relevant to human exposure are developed, assembled, and evaluated, on which health risks and unacceptable risks are determined, with the ultimate goal of reducing exposure and mitigating health risks.
