Yong Liang is an associate professor of the Department of Management Science and Engineering in the School of Economics and Management at Tsinghua University, where he has been since 2014. Prior to joining the faculty of Tsinghua University, he worked for Google's techinical infrastructure team as an operations researcher to optimize Google's fleet, from designing rack configurations to planning service migrations.

He received a B.S. in Engineering Physics from Tsinghua University, an M.S. in Nuclear Engineering from Purdue University. He received his Ph.D. in Industrial Engineering and Operations Research from University of California, Berkeley. His research interests include the energy and IT systems optimization, supply chain management, and analytics. 

Research Interests:
1. Dynamic programming, stochastic optimization, and robust optimization theory and their applications in Operations Management
2. Energy economics, energy markets, and demand-side control

3. Supply chain management
