Nan Liu is an Assistant Professor of Health Policy and Management at Columbia University Mailman School of Public Health. Prior to joining Columbia in 2009, he received a Bachelor's degree in Civil Engineering from Tsinghua University (Beijing, China) in 2002, and an M.S. in Statistics and a Ph.D. in Operations Research from the University of North Carolina at Chapel Hill in 2009.
The overall goal of Dr. Liu's current research is to optimize the logistics and processes of health care delivery. Specifically, his research addresses the questions of how to deliver health services in a more timely, effective and efficient way. On the theory side, he develops mathematical models to optimize patient flow processes and resource utilization through various care pathways in different clinical settings (e.g., ambulatory care, surgical care and emergency care). His applied research examines the impact of contemporary health policies on healthcare operations and public health systems. Trained as both an operations researcher and a data scientist, he draws methodological tools from stochastic modeling, optimization and statistics. He has been collaborating with a variety of healthcare organizations, including NewYork-Presbyterian and several major Community Health Centers in New York City.
