Biography

I am an Assistant Professor at the Institute for Interdisciplinary Information Sciences(IIIS) at Tsinghua University. Before joining Tsinghua, I received my Ph.D. degree from Carnegie Mellon University (2017 - 2022), fortunately advised by Prof. Vipul Goyal. I received my bachelor’s degree in Yao Class at Tsinghua University (2013 - 2017).

My research interest is theoretic cryptography and its application in the real world, especially the efficient multi-party computation.
