Yichen Huang

I am a Ph.D. student in Computer Science at Harvard University under the wise guidance of Prof. Michael Mitzenmacher. I am broadly interested in theoretical computer science, especially in decision making under uncertainty. More concretely, I study uncertainty arising from not knowing the future (online algorithms), from making use of unreliable predictions (learning-augmented algorithms), and from strategic agents with private information (mechanism design). I also enjoy turning observations and insights from real-world phenomena into clean mathematical questions, as well as using theory to guide engineering designs toward practical improvements.

I completed my undergraduate studies during 2020 to 2024 at the University of Oxford, where I had the pleasure of working with Prof. Christian Coester and Prof. Standa Živný. In Spring 2026, I visited Prof. Shaofeng Jiang at Peking University and Prof. Shuran Zheng at Tsinghua University.

I enjoy talking to people with different backgrounds and perspectives. If you are interested in collaborating, or simply want to chat about anything, feel free to reach out at [{firstname}{lastname}]@g.harvard.edu.

Misc

My Erdős number is 3 via the chain YH → Michael Mitzenmacher → Joel H. Spencer → Paul Erdős.

Outside academia, I enjoy playing poker and am learning to boulder. I also spend some time in (Mandarin Chinese) competitive debating and I currently lead the Harvard Chinese Debate Team.
