I am an NUS Presidential Young Professor in the Department of Computer Science at National University of Singapore. Prior to joining NUS, I was a postdoctoral researcher with the theory group at EPFL. I completed my PhD at the University of Pennsylvania and earned my undergraduate degree from Shanghai Jiao Tong University. My research spans a broad range of topics in theoretical computer science and mathematics. Currently, my primary focus is on graph algorithms, with a particular interest in sublinear algorithms and graph sparsification problems.
