About me

I'm a PhD student of Operations Research and Information Engineering at Cornell University. I'm fortunate to be advised by Ziv Scully and work with Alexander Terenin, Peter Frazier, Raul Astudillo, and Su Jia. I have broad interests in decision-making under uncertainty and stochastic control, including topics such as Bayesian optimization, Pandora's Box, multi-armed bandits, and online resource allocation. I obtained my MS degree in transportation planning and engineering from NYU, where I was a research assistant (PhD student) advised by Li Jin on queuing control and application in intelligent transportation systems. Prior to that, I obtained my bachelor's degree in computer science from Yao Class, Institute of Interdisciplinary Information Sciences at Tsinghua University.

My hobbies include table tennis, traveling, and blogging. As a penholder,I won the first place in the 2023 Cornell ORIE Table Tennis Tournament and the third place in the 2022 Cornell CSSA Women's Table Tennis Tournament! I am also a foodie. Feel free to ask me for recommendations on restaurants and attractions in the places I have been to!
