Summary
👤
Senior🎓
Top SchoolNan-Hung Hsieh is a Staff Toxicologist at the California Department of Pesticide Regulation with nine years of experience applying computational toxicology and physiologically‑based kinetic (PBK/PBPK) modeling to human exposure and risk assessment. He bridges regulatory science and quantitative research, having led biomonitoring analyses of pyrethroid exposure using NHANES data and demonstrating higher exposure trends in children. His background includes FDA- and EPA-funded PBPK projects at Texas A&M and published work improving global sensitivity analysis workflows to speed Bayesian PBPK models. Comfortable with both field- and model-driven assessments, he brings practical regulatory review experience and a strong academic foundation (Ph.D. in Bioenvironmental System Engineering) to translate complex toxicokinetic science into actionable policy insights. An atypical strength is his track record of integrating population variability and computational efficiency to make advanced models usable in regulatory decisions.
