“What I cannot create, I do not understand.”

— Richard Feynman

I am a Ph.D. student in Computer Science at University of Southern California, very fortunate to be advised by Prof. Jiapeng Zhang.

During my PhD, I studied communication complexity. My current research seeks quantum advantages that are both provable and practical, with communication complexity offering a promising route to near-term demonstrations.

I am also interested in practical machine learning.
