Tianren Liu (刘天任)

Ph.D. Candidate, EECS, MIT

I am a PhD student in MIT Theory of Computation group since 2014. I am working on cryptography, advised by Vinod Vaikuntanathan.

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

I'm going to join UW as a postdoc researcher under Huijia (Rachel) Lin.

So far, my research focuses on

  • information theoretic cryptography;
  • secret sharing (both IT and computational);
  • (im)possibility of basing cryptography on NP-hardness.
