For over two decades, Dr. Ng’s research and professional work has focused on inequities in health care access and quality, quality of care measurement, patient-reported health and functional outcomes, opioid use disorder, and Medicare and Medicaid policy. A mixed-methods researcher, Dr. Ng has directed and published research on health inequities among Medicare and Medicaid beneficiaries, health care access and quality gaps among underserved populations, conceptual underpinnings of health inequities, and best practices in care across diverse settings – from pediatric immunizations to chronic condition management in older adults.

Recently, her work on health inequities and opioid prescribing practices supported federal policy changes that improve health outcomes.
