Hello, this is Han
I am the Director of CyberPUNK Lab and an Assistant Professor (Lecturer) in the School of Electronics & Computer Science (ECS) at the University of Southampton. I am also a member of the Cyber Security group. My research interests are AI Security and Privacy.
Previously, I was a Research Fellow at the University of Birmingham, working with Prof. Aad van Moorsel on the EPSRC-funded AGENCY project, and a Research Associate at Newcastle University on the EPSRC-funded FinTrust project. I received the Alan Turing Institute’s Post-Doctoral Enrichment Award 2022.
📣 🎓 PhD Opportunities at ECS, University of Southampton 🇬🇧 Prospective PhD and visiting students interested in AI security and privacy are welcome to contact me via email.
Further details are available on my CV page.
