I am an Assistant Professor of CUHK, SEEM. I study service operations and applied probability.
Previously, I was a Principal Researcher at the University of Chicago Booth School of Business, mentored by Professor Amy Ward. I received my Ph.D. from the National University of Singapore in 2025, and B.E. in 2020 from the Shanghai Jiao Tong University. I also worked with Professor Timothy Chan from the University of Toronto, and Professor Xu Sun from the Miami Herbert Business School during my research training.
Opportunities
I am looking for motivated PhD students with strong mathematical and technical skills to work with me. My previous projects are listed here. If you're interested, please feel free to email me your CV, transcript(s), and a brief description of your research interests. I review all inquires but may only be able to reply to selected candidates.
Research Interests
My research uses stochastic modeling and control, queueing theory, optimization, and data analytics to tackle complex operational challenges, with a focus on:
- Modern service operations: Improve service environments featured by innovative business models, initiatives, and emerging technologies, e.g., on-demand workforces, drones, and AI-augmented service systems.
- Socially responsible operations: Enhance service systems to meet societal needs and create public impact, e.g., cardiac arrest response, community first responder programs, and lift-trap rescue.
- Data-driven queueing control: Develop data-driven and provably "optimal" policies for queueing systems with unknown primitives, e.g., arrival and reneging processes.
My research works have been published in top outlets, including Operations Research, Manufacturing & Service Operations Management, and Production & Operations Management, and have received notable recognitions, including the INFORMS SOLA Best Student Paper Award, and a finalist of the POMS-HK Best Student Paper Award.
