Hello! I’m Xilai Liu, a fourth-year PhD student at ICT, CAS, coadvised by Prof. Gaogang Xie and Prof. Tong Yang. I also work closely with Prof. Heng Pan. Before ICT, I was an undergrate at Peking University, where I received my B.Eng. degree in Computer Science and B.S. degree in Psychology. My research interests include programmable network and data sketches. (I love the game Genshin Impact and its character Ganyu.)
