Sylvia Shi, MPH, is an associate scientist within Health Services Research in the Surveillance & Health Equity Science department at the American Cancer Society (ACS).  With a broad interest in chronic diseases, she investigates the impact of health policies on economic burden, access to and receipt of care, and health-related quality of life, with the goal of improving outcomes for patients with cancer.

Research focus and accomplishments

Shi uses quantitative methods to understand the associations and trends of different state and national health policies on access to care, service utilization, and outcomes. She’s also interested in using modelling approaches to measure the effects of interventions in cancer prevention, diagnosis, and treatment to inform health care decision making.

Her recent collaborations include studies evaluating health insurance coverage, Medicaid expansion under the Affordable Care Act, and cancer outcomes.
