Dr. Daw studies how policies affect the barriers faced by reproductive-aged and pregnant women in accessing health services, from gaining health insurance to connecting with providers and ultimately, receiving high-quality care. Her current research agenda focuses on how Medicaid policy changes and new health care delivery models can promote improved health care access, quality, and health outcomes in the extended postpartum period. Dr. Daw also studies prescription drug coverage policy and access to medicines in the U.S., Canada, and other high-income countries. Her work has been published in leading medical, health services, and policy research journals including JAMA, CMAJ, Obstetrics & Gynecology, Health Affairs, and the Journal of Health Policy, Politics and Law.
