Yuyang Song is an undergraduate student majoring in computer science of Wuyuzhang Honour College in Sichuan University, expected to graduate in June 2026 under the supervision of Prof.Mingjie tang, Sichuan University and Prof.Jianguo Wang, Purdue University. Currently, his research interest lies in efficient reasoning LLMs, particularly LLM based Database System Design and Optimization.
I am eager to pursue admission to a PhD program in Fall 2026 to deepen my expertise and make meaningful contributions.
