Biography

I am a fifth year Ph.D. student at Carnegie Mellon University (2017 - Present), fortunately advised by Prof. Vipul Goyal. My research interest is theoretic cryptography and its application in the real world, especially the efficient multi-party computation.

This summer, I am an intern at NTT Research, Sunnyvale and work with Prof. Vipul Goyal on the communication-efficient multi-party computation.

In Summer 2020, I was an intern in the AI Research team at J.P. Morgan, New York and worked with Antigoni Polychroniadou on the communication-efficient multi-party computation.

I received my bachelor’s degree in Yao Class at Tsinghua University (2013 - 2017). During my undergraduate, I visited Aarhus University in Spring 2016 and worked with Claudio Orlandi on order revealing encryption.
