Applied Probability; Stochastic Modeling and Optimization; Numerical Methods and Algorithm.

Professor Jiheng Zhang is the Department Head of Industrial Engineering and Decision Analytics (IEDA) at the Hong Kong University of Science and Technology (HKUST). 

Prof. Zhang joined IEDA as an Assistant Professor in 2009, and was promoted to Associate Professor in 2015 and then to full Professor in 2020. His research interests are in the areas of service operations management, queueing system and applied probability. He is an outstanding scholar in the field of Stochastic Modelling and Optimization, Statistical Learning, Numerical Methods and Algorithm, as evidenced by publishing ten papers in leading journals of his discipline since his substantiation, including Management Science, Operations Research, and Mathematics of Operations Research. He has been serving as Associate Editor for Operations Research, Stochastic Systems, and Queueing Models and Service Management, and an editorial board member for Probability in the Engineering and Informational Sciences. 

Prof. Zhang received both Ph.D. and M.S. degrees in Operations Research from Georgia Institute of Technology (2009, 2005), M.S. degree in Mathematics from the Ohio State University (2003), and B.S. degree in Mathematics in Nanjing University (2002).
