I am currently a first-year Ph.D. student in Computer Science at the University of North Carolina at Chapel Hill (UNITES @ UNC), advised by Prof. Tianlong Chen. Before joining UNC, I received my B.S. degree in Computer Science and Technology from the University of Science and Technology of China (USTC). My research interests lie in efficient and reliable machine learning, including building intelligent agent systems for diverse applications such as robotic automation, improving the scaling efficiency and reliability of LLM through techniques like Mixture of Experts (MoE).
