My research focuses on privately managed insurance markets, including employer-sponsored insurance, Medicaid managed care, and Medicare Advantage. I study, first, what policy and market factors influence what private insurers and employers choose to offer in these markets. And second, how those choices impact financial security and access for enrollees, with a particular focus on access to mental health and substance use disorder treatments.
