Hi! I am a principal researcher at the University of Chicago Booth School of Business, working with Professor Amy Ward. I received my Ph.D. from the National University of Singapore in 2025, and B.E. from the Shanghai Jiao Tong University in 2020.
I will be joining CUHK, SEEM as an Assistant Professor in November 2025.
Research Interests
My research leverages 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.
