Xiaowei Zhang

Hong Kong University of Science and Technology

I am an Associate Professor at HKUST, jointly appointed in the Department of Industrial Engineering and Decision Analytics and the Department of Economics, and the Academic Director of the MSc in FinTech program. I serve as an Associate Editor for several leading journals in the field, including Management Science, Operations Research, Navel Research Logistics, and Queueing Systems.

My research focuses on developing innovative methodologies for data-driven decision-making, leveraging the unprecedented access to data and computational resources. By integrating advanced techniques from simulation, stochastics, and machine learning, I address complex challenges in business operations, finance, and digital economy, while investigating the transformative potential of AI technologies in these domains.
