I study sequential decision-making under uncertainty: how to make decisions today while accounting for their consequences over time. My research combines stochastic optimization, structural analysis, and data-driven optimization, with applications in supply chains, healthcare, nonprofit operations, and sustainability.

My recent research asks how AI and data science can reshape the way we model and solve sequential decision problems. I am particularly interested in learning representations of operational systems and predicting the consequences of actions to support better decisions.

Join my group. I welcome self-motivated Ph.D. students and research assistants interested in operations research, AI, and data-driven decision-making. Students with backgrounds in mathematics, statistics, physics, computer science, or related fields are encouraged to contact me at twang533@cityu.edu.hk
