I explore policy implications through review of administrative claims data as well as publicly available secondary datasets.  Intended and unintended consequences of policy implementations are a primary focus of my research along with utilization and resource use resulting from global changes to health care management.  Disease areas include opioid misuse and abuse, asthma, diabetes, and mental health.
