I am a second-year Master’s student of Computer Science and Technology at Sun Yat-sen University, under the supervision of Prof. Xianwei Zhang. Previously I completed my Bachelor’s degree at South China University of Technology (SCUT).

I am particularly interested in building practical, scalable and efficient systems for machine learning (MLSys) like serving system. Currently, my research focuses on optimizing KV Cache management, developing efficient inference scheduling strategies, and improving RLVR efficiency through advanced sampling techniques.

I warmly welcome any academic discussions and collaborations! If you are interested in my research work or have suitable internship opportunities, please feel free to contact me through:
