TONGYANG LI

Welcome!

I am an assistant professor at the Center on Frontiers of Computing Studies, Peking University. Previously I was a postdoctoral associate at the Center for Theoretical Physics, Massachusetts Institute of Technology during 2020-2021. I received my Ph.D. degree from the Department of Computer Science, University of Maryland in 2020, and I received Bachelor of Engineering from the Institute for Interdisciplinary Information Sciences, Tsinghua University and Bachelor of Science from the Department of Mathematical Sciences, Tsinghua University, both in 2015.

My research investigates interdisciplinary subjects among quantum computing, machine learning, and theoretical computer science, with the focus on designing quantum algorithms for machine learning and optimization. I am also interested in quantum simulation, quantum query complexity, and quantum walks.
