About Me

I am a third-year PhD student in Institute for Interdisciplinary Information Science (Yao Class) at Tsinghua University, advised by Prof. Huanchen Zhang. Before joining Tsinghua, I obtained my BS at Yuanpei College of Peking University, advised by Prof. Tong Yang. My research interests mainly lie in the fields of designing lighting-fast data structures and algorithms for storage, databases, and machine learning system.
