EXPERTISE/RESEARCH/TEACHING INTERESTS

Professor Liu studies operations management topics in service industries (e.g., health care, retail and transport). His current research focuses on the design and control of service systems, with capacity constraints and complex customer behaviors. One particular application area of his research is health care, in which he addresses questions of how to deliver health services in a more timely, effective and efficient way. Trained as both an operations researcher and a data scientist, he draws methodological tools from stochastic modeling, optimization and statistics. Prior to joining the Carroll School of Management, Professor Liu was on the faculty of Health Policy and Management Department at Columbia University.
