Ji-Yeun Park’s teaching focuses on health behavior theories, social and behavioral health sciences, and research methods. The primary goal of her teaching is to provide rich learning opportunities that encourage students to think more deeply and critically about public health issues. She enjoys bringing Christian faith into the classroom so that students can better understand how the Christian faith shapes public health. 

Park’s research interests include substance use, with an emphasis on e-cigarettes, marijuana, and opioids, and substance abuse problems. Her work focuses on 1) examining the prevalence and determinants of substance use, 2) assessing how drug policies affect substance use behaviors, and 3) addressing substance abuse and related problems. Park conducted post-doctoral research at the Duke University Medical Center and University of California San Diego.
