Professor Jiangang Jim Dai is the Leon C. Welch Professor of Engineering in the School of Operations Research and Information Engineering, Cornell University. He is also the Dean of School of Data Science, Chinese University of Hong Kong, Shenzhen. Prior joining Cornell in 2012, Professor Dai held the Chandler Family Chair of Industrial and Systems Engineering at Georgia Institute of Technology, where he was a faculty member from 1990 to 2012, and received the title of Edenfield Professor in 2007. He was a Special Term Professor at the School of Economics and Management, Tsinghua University from 2002 to July 2018, and James Riley Distinguished Visiting Professor at the National University of Singapore from 2009 to 2011.

Professor Dai is an international leading scholar in operations research. Most of his former PhD students obtained faculty positions at internationally renowned universities. Professor Dai has received a number of awards for his research contributions. He was honored with the 1994 Young Investigator Award (formerly the Presidential Young Scientist Award) and the 1998 Erlang Prize from the INFORMS Applied Probability Society for his outstanding academic achievement. In 1997 and 2017, Professor Dai was awarded the Best Paper Award by the INFORMS Applied Probability Society. He is the only scholar to have won this award twice by 2018. In 2018, Professor Dai received the 2018 ACM SIGMETRICS Achievement Award. Professor Dai served as the Editor-In-Chief for Mathematics of Operations Research (MOR), the leading academic journal in operations research, from 2012 to 2019.
