I am a PhD student in the Decision, Risk, and Operations (DRO) division at Columbia Business School. I enjoy building (sensible) mathematical models to explain existing phenomena and help decision-making. Currently, I am working with Hongyao Ma on pricing problems in ride-sharing markets.

I received my bachelor’s degree in computer science from Institute for Interdisciplinary Information Sciences (Yao Class) at Tsinghua University. During my undergraduate study, I spent six months at Caltech, where I worked with Adam Wierman on online optimization; I also spent a summer at University of Michigan, where I worked with Grant Schoenebeck on mechanism design.

My name in International Phonetic Alphabet (IPA): [tʂʰən˧˥ kʰaɪ˨˩˧ y˧˥]. “Yu” sounds like the French word “tu” without “t”.
