👋 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) and search systems. My research currently focus on:

1. I research the effectiveness and vulnerabilities of LLM-based ranking systems, also where the systems are applied, e.g., RAG systems.
2. I also study how the information seeking process and behavior have evolved in the modern (or contemporary) information environment, aiming to enhance the theoretical understanding of modern IR.
