Research Interests

Nearly 80% of U.S. adults meet criteria for overweight/obesity. All three evidence-based obesity treatment options – behavioral weight management, obesity medications and bariatric surgery – are significantly underutilized. As a surgeon scientist, my long-term goal is to optimize access and outcomes of obesity care for adults with overweight/obesity. Our group uses quantitative (e.g., database analysis) and qualitative research methods (e.g., interviews and focus groups) and conducts clinical trials aimed at improving outcomes for adults with obesity. We are also focused on addressing socioeconomic disparities pertaining to obesity treatment and are currently conducting a mixed-methods analysis of patients who have undergone bariatric surgery in an effort to understand barriers to optimal outcomes. Our research group is located at both the University of Wisconsin-Madison and William S. Middleton Veterans Memorial Hospital.
