Ph.D. in ICME, Stanford Univerisity Office: Huang Engineering Center |

I am a Ph.D. student in Institute for Computational and Mathematical Engineering(ICME) at Stanford Univeristy. I am co-advised by Chris Ré and Michael Mahoney. My research interest lies in randomized linear algebra, optimization and machine learning. In particular I am interested in leveraging tools from randomized linear algebra to provide efficient and scalable solutions for large-scale optimization and learning problems. Before joining Stanford, I recieved my B.S. in Mathematics from Fudan University.
