Tianren Liu 刘天任

I'm a postdoc researcher in UW, mentored by Huijia (Rachel) Lin.

I was a PhD student in MIT Theory of Computation group, advised by Vinod Vaikuntanathan, and received my PhD degree in 2019.

I received my bachelor degree in Tsinghua University Yao Class, advised by John Steinberger.

So far, my research focuses on

  • information theoretic (IT) cryptography;
  • secret sharing (mainly IT);
  • multi-party computation (both IT and computational);
  • practical cryptography (from an IT perspective);
  • (im)possibility of basing cryptography on NP-hardness.
