Clayton, VIC 3800, Australia

I am interested in mathematical aspects of cybersecurity, particularly around cryptography. My current research focuses are quantum-safe cryptography (particularly, from lattices and hash functions), privacy-enhancing technologies, zero-knowledge proofs and blockchain protocols as well as their real-life applications to establish various security features such as confidentiality, integrity, privacy, anonymity and accountability in practice. I have also worked on symmetric-key cryptography and classical public-key cryptography.

I currently work as a lecturer at the Faculty of Information Technology, Monash University, where I also serve as the Deputy Course Director of Master of Cybersecurity and the Deputy Director of Post-Quantum Cryptography in the Indo-Pacific (PQCIP) Program. Before that, I was a post-doc at Monash and CSIRO’s Data61 jointly. I also did a research internship at IBM Research, Zurich, hosted by Vadim Lyubashevsky. I completed my PhD at Monash under the supervision of Ron Steinfeld, Joseph Liu and Dongxi Liu.

I organise Monash Software Systems and Cybersecurity (SSC) Seminars. If you are interested in cutting-edge research in cybersecurity, sofware engineering and data engineering, see our website for past and upcoming events.

I have multiple PhD scholarships available. Please refer to supervision.

This webpage is currently under development. If you spot any issues, please contact me via email (provided at the end of the page).
