Zeyan Liew

Zeyan Liew is an Associate Professor of Epidemiology at the Yale School of Public Health, specializing in Environmental Health Sciences. His research focuses on how exposures during critical developmental periods influence lifelong disease risks, particularly neurodevelopmental outcomes.

• PhD in Epidemiology from UCLA (2014)
• MPH in Environmental Health Sciences from UCLA (2011)

Research interests include environmental and perinatal epidemiology, endocrine disruptors, neurotoxicants, and methodological innovations in observational studies. He leads NIH-funded studies on prenatal exposures to chemicals and their impacts on conditions like autism, cerebral palsy, and neurodevelopmental disorders.

Recent article trends explore PFAS exposure, acetaminophen in pregnancy, and air pollution effects on neurodevelopment, using causal inference and advanced statistical modeling across Danish and California cohorts.

• Early Career Investigator Research Award (YSPH, 2024)
• NIH R01 grants (NIEHS & NICHD, 2023-2024)
• Climate Change and Health Pilot Grant (2024)

He advises MPH/PhD students in environmental epidemiology and leads the Liew Lab, collaborating with the Danish National Birth Cohort, INUENDO Cohort, and Yale-Mayo FDA CERSI. Current projects include Neuro-APAP Study and EXPOSE CP Study.
