Dr. Donglei Du, currently serving as the Associate Dean—Research & Graduate Studies, is a professor in Operations Research at the Faculty of Business Administration (FBA), University of New Brunswick (UNB), Canada. His main research interests are combinatorial optimization, approximations algorithms, robust optimization, social network analysis, algorithmic game theory, supply chain management, facility location, and machine scheduling.

His publications have appeared in top-tier journals, including Operations Research, Algorithmica, SIAM Journal on Discrete Mathematics, European Journal of Operation Research, Omega etc. He received several awards from UNB at both the university and faculty levels, including the University Research Scholar (UNB, 2014), University Merit Award (UNB, twice, 2006 and 2012), Excellence in Research Award (FBA, 2007), and Annual Research Award (FBA, 2004).

Donglei Du previously held a position at the Institute of Applied Mathematics in the Chinese Academy of Sciences.

Besides his theoretical interests, Dr. Donglei Du is also involved in a number of practical projects that utilize his optimization and statistical techniques, such as the design of the Scheduling and Dispatching System for Day & Ross during 2004-2006.
