About Me

Hi I'm Zhicong Huang (黄智聪).

I obtained my Ph.D. from École Polytechnique Fédérale de Lausanne (EPFL), Switzerland (under the supervision of Prof. Jean-Pierre Hubaux and Prof. Jacques Fellay), and my bachelor degree in computer science from Peking University, China.

My research interests are security and privacy, applied cryptography, and trustworthy AI.
