I am currently a lecturer at the School of Computing and Information Technology of the University of Wollongong. Before that, I was a postdoctoral fellow at the University of Hong Kong. I earned my PhD degree in Feb 2020 from the Hong Kong Polytechnic University, where I was advised by Prof. Man Ho Au.

I am delighted to be selected as a 2024 ARC Discovery Early Career Researcher Award (DECRA) for my research in the area of anonymous authentication.

I am broadly interested in applied cryptography, including:

  • Privacy-Preserving Cryptography
  • Blockchain Technology & Cryptocurrency
  • Lattice-based Cryptography

I am looking for self-motivated PhD students (full PhD scholarship starting from 2024) in cryptography. Please send me an email if you are interested.
