Megan Schuler is a health policy researcher at the RAND Corporation. Methodologically, her research primarily focuses on causal inference methods which facilitate rigorous analysis of observational health data. As a co-investigator affiliated with RAND’s Opioid Policy Tools and Information Center (OPTIC), a primary focus of her current work is opioid policy research. In particular, her work seeks to develop and disseminate state of the art statistical methods for evaluating the effectiveness of state and federal opioid policies. Another central research interest is heterogeneity in substance use and mental health behaviors, disorders, and treatment, with respect to variation across age and population subgroups. Her current research focuses on substance use disparities among sexual minorities (e.g., gay, lesbian, bisexual individuals). Her ongoing work has characterized notable variation in substance use behaviors across sexual minority subgroups and identified differential risk factors and etiological pathways that contribute to these disparities.
