Zeyan Liew, PhD, MPH

Associate Professor of Epidemiology (Environmental Health Sciences)



Dr. Liew is an environmental and perinatal epidemiologist and a research methodologist. A core focus of his work is understanding how exposures that occur during critical and vulnerable periods of development may shape disease risks and influence health outcomes throughout our life span. Dr. Liew is leading numerous studies with funding from the NIH to evaluate whether fetal exposures to endocrine disrupting compounds and/or neurotoxicants could harm fetal brain development leading to neurological disorders or impaired neuropsychological function in childhood and young adulthood. He is also interested in methodological research, especially the development of novel study designs and analytical techniques that could help us better address biases in observational studies or research using “real-world” data.
