I am a PhD candidate in Computing and Information Systems at the University of Melbourne, supervised by Prof. Christopher Leckie, Prof. Sarah M. Erfani, and Dr. Hanxun Huang. My research focuses on trustworthy AI, with an emphasis on robustness, fairness, adversarial reliability, and hallucination detection in vision-language models.
I am particularly interested in understanding how multimodal models fail under distribution shifts, spurious correlations, adversarial perturbations, and visually unsupported generation, and in developing practical methods to improve their reliability.
