Bio

Xuanzi (Shirley) Qin, PhD, MSPH is an Assistant Professor in the Department of Health Policy and Management at the University of Maryland College Park. Dr. Qin received her PhD degree in Health Services Research, Policy & Administration with a focus on health economics and clinical outcomes from University of Minnesota. She received her MSPH in Health Policy and Health Services Research from Emory University. She received a Bachelor of Engineering degree in Biopharmaceutical Engineering and a Bachelor of Economics degree in Finance from South China University of Technology. During her PhD training, she has worked at the Research Data Assistance Center (ResDAC) for 5 years, providing analytical assistance to CMS Data Training Workshops and developing KnowledgeBase articles about the use of various Medicare and Medicaid administrative data (Medicare enrollment data, Medicare inpatient/skilled nursing facility/carrier/outpatient claims, Medicare Part D event file, Medicare Part D formulary and plan characteristic files, Medicare Advantage encounter data, nursing home assessment data (MDS 2.0/3.0), Medicaid MAX/TAF).

Dr Qin's research has an overarching theme that explores how health decisions were affected by various factors, including patient preferences, physician preferences, clinical factors and market factors. Her previous research investigated how mammography screening utilization was potentially affected by guidelines, women's screening experience, women's perceptions of the harms and benefits of mammograms, and their attitudes about getting a mammogram. Her dissertation examined how drug patent, out-of-pocket costs, subsidies and clinical factors affect cancer treatment decisions, bridging economic perspectives and clinical perspectives. Her ongoing projects focus on Medicare Part D benefit design, genetic testing (tumor sequencing), and the impacts of cancer on aging.
