I am Qijia He, a first-year Ph.D. student in the Department of Electrical and Computer Engineering at The Ohio State University, advised by Prof. Yingbin Liang. I received my bachelor degree from the Southern University of Science and Technology (SUSTech), where I was advised by Prof. Fang Kong and Prof. Yifang Ma. In 2023, I spent a semester as an exchange student at Stony Brook University. My research interests include bandit algorithms and reinforcement learning for large language models.
