Then he obtained his PhD in Policy Analysis at Pardee RAND Graduate School in the U.S from 2008 to 2013. He is an Assistant Professor and a PhD supervisor at Department of Kinesiology and Community Health at College of Applied Health Sciences in University of Illinois. His research interests are public health and policy intervention. In recent years, he hosted and participated 14 key research project from the United States Department of Agriculture and the National Institutes of Health. He has been published 90 articles in international academic journals and 43 abstracts in international academic conferences.



This study projected the societal cost and benefit of an expansion of a water access intervention that promotes lunchtime plain water consumption by placing water dispensers in New York school cafeterias to all schools nationwide. A decision model was constructed to simulate two events under Markov chain processes—placing water dispensers at lunch times in school cafeterias nationwide versus no action. The incremental cost pertained to water dispenser purchase and maintenance, whereas the incremental benefit was resulted from cases of childhood overweight/obesity prevented and corresponding lifetime direct (medical) and indirect costs saved. Based on the decision model, the estimated incremental cost of the school-based water access intervention is $18 per student, and the corresponding incremental benefit is $192, resulting in a net benefit of $174 per student. Nationwide adoption of the intervention would prevent 0.57 million cases of childhood overweight, resulting in a lifetime cost saving totaling $13.1 billion. The New York school-based water access intervention, if adopted nationwide, may have a considerably favorable benefit-cost portfolio.
