Qirun Zeng
Ph.D. candidate in Computer Science at City University of Hong Kong
I study learning and decision-making under uncertainty, focusing on bandit learning, feedback design, and adversarial robustness. My interests also include sequential inference and combinatorial optimization. My advisor is Prof. Jinhang Zuo.
Previously, I worked as a research assistant with Prof. Sibo Wang at the Chinese University of Hong Kong from July to October 2024. I received my bachelor’s degree in Computer Science and Technology from the School of the Gifted Young at the University of Science and Technology of China, where I was advised by Prof. Xue Chen and Prof. Jinhang Zuo.
