I am currently pursuing a Ph.D. degree in Computer Science at Wuhan University (WHU) under the supervision of Prof. Lefei Zhang, and expect to graduate in 2027. During this period, I am also fortunate to receive valuable guidance from Dr. Sen Zhang, Dr. Liang Ding, and Prof. Dacheng Tao. Before that, I received my bachelor’s degree in Mathematical Sciences at the University of Electronic Science and Technology of China (UESTC) in 2022, under the supervision of Prof. Xile Zhao. I am sincerely grateful to all my mentors for their invaluable guidance, support, and inspiration throughout my academic journey.

I have authored or co-authored over 10 papers published in top-tier international journals and conferences, including IEEE TPAMI, ICML, NeurIPS, CVPR, ICCV, and EMNLP. In addition, I am supported by the Fundamental Research Project for Young Professional from NSFC (国自然博士生基金, PR). I have also received several honors, including the China Remote Sensing Outstanding Achievement First-Class Prize (2025 中国遥感优秀成果一等奖, PR) and the VALSE 2025 Popular Poster Award (VALSE 2025人气海报奖, PR).

My current research interests mainly focus on Reinforcement Learning (RL) for LLMs, including Reinforcement Learning from Human Feedback (RLHF), reasoning RL, and agentic RL. Previously, my research primarily focused on tensor modeling and computing, high-dimensional image processing, and remote sensing.

📧 I am open to collaboration and welcome inquiries from anyone interested in my research topics. Feel free to reach out via szmyc1@163.com or miaoyuchun@whu.edu.cn.
