Profile

Ning Cai joined the Department of Industrial Engineering and Decision Analytics at the Hong Kong University of Science and Technology as an Assistant Professor in 2008. He was promoted to Associate Professor in 2014 and was further promoted to full Professor in 2020. He received both M.S. and Ph.D. in operations research in the Department of Industrial Engineering and Operations Research at Columbia University and both B.S. and M.S. in probability and statistics in the School of Mathematical Sciences at Peking University.

Ning Cai was the first Academic Director of the new Master of Science Program in Financial Technology (MSc in FinTech) jointly offered by School of Business and Management, School of Engineering, and School of Science. Currently, he is the Director of the Financial Engineering and FinTech Laboratory in the Department of Industrial Engineering and Decision Analytics.

Ning Cai's research interests include financial engineering, FinTech, applied probability, and stochastic modeling. He has published papers in the top-tier journals such as Management Science, Operations Research, Mathematical Finance, Mathematics of Operations Research, and INFORMS Journal on Computing.

Currently, he serves as the associate editor for Operations Research, Operations Research Letters, and IMA Journal of Management Mathematics and also serves on the editorial board of Stochastic Models and Probability in the Engineering and Informational Sciences.

Since 2018, he has also served as associate editor for Digital Financea Springer journal that focuses on publishing high-quality papers on smart data analytics, investment innovation, and financial technology.
