About Me

I am a PhD student at the University of Queensland, working under the supervision of A/Prof. Guangdong Bai and Dr. Jason Xue. I’m currently serving as the HDR representative for the CSS discipline. My research is generously supported by the RTP Scholarship and CSIRO’s Data61 Top-up Scholarship. I am also honored with the Google PhD Fellowship, 2024.

Research Interests

My research interests are to tackle real-world security & privacy issues of machine learning systems in a formally verifiable manner. My works have been published in leading venues, including IEEE S&P, ACM CCS, USENIX Security, NeurIPS, WWW, WACV, and IEEE TCSS. I also work closely with my colleague Zhongkui Ma on NNV. Some of my recent projects include:
