My background and training are in health services research and health economics. I conduct policy-driven research using complex and large data. My primary research area is health policy and prevention, particularly focusing on socioeconomically disadvantaged population. I recently completed a project funded by Academy Health to study the economic impact of Affordable Care Act (ACA) reform on cancer screenings of Medicare population. I recently developed an active research agenda on impacts of the ACA reforms on low-income women and children. I am a co-investigator of a Patient‑Centered Outcomes Research Institute (PCORI)-funded project studying the patient-centered outcomes of Medicaid children with disabilities. Currently, I am a Principal Investigator of a project that evaluates the role ACA plays in low-income women’s fertility and contraceptive behaviors.
