Human health risk assessment is a rapidly growing multidisciplinary field that has broad utility in a variety of sectors, including occupational safety and health, the chemical and pharmaceutical industries, and regulatory agencies, and plays key roles in informing daily decision making affecting millions of dollars in commerce. The Lautenberg Chemical Safety for the 21st Century Act enacted in 2016 accentuates the importance of risk assessment in chemical regulation to protect public health from chemical exposure. Dr. Shao’s team aims to develop innovative modeling strategies to advance quantitative human health risk assessment in support of chemical regulation. Currently, we have two important projects: The first one is to build a next-generation dose-response modeling system to improve current dose-response assessment practice. Quantitative and programming skills are desired for this project. The second one focuses on developing a probabilistic risk assessment framework to enhance risk-based decision making for food safety regulation in China using inorganic arsenic in rice as a case study. This project is more suitable for students who are interested in economic analysis (especially, benefit-cost analysis) and chemical regulation and policy.
