Dr. Wang’s research surrounds the theme of using modeling to integrate the evidence base to inform policy and practice guidelines. Specifically, she is interested in the distribution of modifiable risk factors (e.g., diet, exercise, and disease screening) and their joint implications on disease burden in the whole population and between demographic subgroups.
Her present research focuses on the obesity epidemic in adults and in children. Supported by the Robert Wood Johnson Foundation, Dr. Wang has assessed behavioral and environmental determinants of energy balance (energy intake vs. energy expenditure) and an online tool to evaluate how various population-wide strategies and policies may help fighting obesity in children and adolescents. A key behavioral aspect she has worked on is the trend and caloric implications of the rapidly rising intake of sugar-sweetened beverages among US adults and youth. She has published several papers which evaluated the health and economic impacts of potential policy interventions such as levying excise taxes on sugar-sweetened beverages and imposing portion size restrictions.
Dr. Wang is co-Director of the Obesity Prevention Initiative at Columbia Mailman School of Public Health, and Fellow of The Obesity Society and New York Academy of Medicine.
