NIAN LIU / 刘 念

I am a second year Ph.D. student in the School of Computing at National University of Singapore (NUS) with President’s Graduate Fellowship, advised by Prof. Xavier Bresson. Before joining NUS, I received my M.S. and B.E. at Beijing University of Posts and Telecommunications, supervised by Prof. Chuan Shi and Prof. Xiao Wang.
My research interests include Graph Neural Network, Graph Transformer, Graph Signal Processing and Graph Self-supervised Learning. Now, I am engaging in the graph diffusion generation technique and its applications on AI4Material.
