If you have difficulty saying my name, it is pronounced similarly to "shout yeah" without the "t". Some friends just call me "XY".

Hi! I am a rising fifth-year Ph.D. student at the MIT Operations Research Center. I am co-advised by Professor David Simchi-Levi and Professor James Orlin. My current research interests lie broadly in online algorithms, reinforcement learning, data-driven revenue management and supply chain optimization.

Prior to coming to MIT, I finished my undergrad with summa cum laude in 2017 at New York University and NYU Shanghai, with double majors in Honors Mathematics and Interactive Media Arts. In summer 2015, I studied at Budapest Semesters in Mathematics. In summer 2014, I studied with full scholarship in the Business Entrepreneurship program at Tel Aviv University. Also in 2014, my friends and I organized the largest international college hackathon in China at that time, the inaugural HackShanghai. During the same year, I was a Legal Intern at Citibank (China) in Shanghai.

I am on the 2021-2022 academic job market and looking for tenure-track positions.

I was a Research Intern at Google Research (Cambridge office) in summer 2021. I was a Research Intern at Microsoft Research AI (Redmond office) in summer 2020, and a Quantitative Analyst Intern at D.E. Shaw in New York City in summer 2019.
