My research interests include machine learning, optimization, and computer vision. My current research focuses on large language models for basic education, as well as efficient pre-training and post-training techniques. Before joining Beijing Normal University, I was a Boya Postdoctoral Researcher at Peking University, working with Prof. Zhouchen Lin. I received my Ph.D. in Computer Science from Beijing Jiaotong University in 2017, under the supervision of Prof. Zhouchen Lin and Prof. Jian Yu.

🔥 Recruitment
