👋 Hi there! I’m a first-year PhD student at the School of Computing Technologies, RMIT University. As a recipient of a full PhD scholarship and a student member of the ARC Centre of Excellence for Automated Decision-Making and Society (ADM+S), I’m lucky to work under the guidance of Dr. Danula Hettiachchi and Dr. Damiano Spina.

I earned a Master’s degree in Computer Science from The University of Queensland (UQ). At UQ, I also worked as a summer intern and a casual research assistant (RA) at the The Information Engineering Lab (ieLab), supervised by Prof. Guido Zuccon. My research focused on large language model (LLM)-based re-rankers, particularly investigating the impact of prompt variations on their performance.

My research interests lie in information retrieval (IR), search systems and user behaviors. I am currently focusing on these two aspects of IR:

1. I investigate the effectiveness and vulnerabilities of LLM-based ranking systems, also their applications in, e.g., RAG systems.
2. I also explore how information-seeking behaviors have changed and been influenced by non-traditional search interfaces and modern information environments.
