Dr. YoonKyung Chung is a Principal Research Scientist at the Harvey L. Neiman Health Policy Institute. Her main role in the HPI team is to lead and conduct research using large datasets to understand the value and role of radiology in evolving health care delivery and payment systems. With a background in economics, she has extensive experience exploring questions using quantitative methods: finding clear and accurate ways to understand and communicate how patient outcomes respond to how providers are delivering care in complex policy environments.
Prior to joining HPI, she worked as the Senior Economist at the Robert Graham Center, primarily studying the impact of primary care physician practice patterns on health care costs and patient outcomes using Medicare claims. She has also led research on developing a new quality measure using electronic health records data. Dr Chung received her doctorate in Economics from the University of California, Davis.
