Biography:

Dr Li is an associate Professor of Management School at the University of Science and Technology of China. He served as a postdoctoral researcher in Probability Theory and Mathematical Statistics (2008-2010) and serves as an associate Professor of Management School since 2010. He worked as a Visiting Scholar in System Analysis Lab at the Aalto University in 2012, and a Visiting Professor in Faculty of Economics and Business at the Zagreb University in 2014. 

His research mainly focuses on data envelopment analysis (DEA) methodology and its applications. He has published over 40 academic articles in research journals such as European Journal of Operational Research, Annals of Operations Research and Omega. He serves as peer reviewers for a number of research journals such as European Journal of Operational Research and Omega, and awarded the Best reviewer from Omega in 2013. 

His research is supported by many funds from National Natural Science Foundation of China and Chinese Academy of Sciences. He is a member of Youth Innovation Promotion Association of Chinese Academy of Sciences.
