About Me

Aloha! I am a Postdoctoral Research Associate at the Australian Artificial Intelligence Institute (AAII), University of Technology Sydney (UTS), working with Prof. Jie Lu. I recently submitted my Ph.D. thesis at UTS (pending examination and conferral), where I was also supervised by Prof. Jie Lu at AAII.

Previously, I obtained my Master of Philosophy (M.Phil.) degree from the University of Sydney, where I was supervised by Dr. Tongliang Liu.

My primary research interests include:

• Learning with Concept Drift
• LLM Hallucination Detection
• Learning with Label Noise

Outside of academia, I enjoy reading historical books, solving challenges, and chatting with interesting people.
