I am a Ph.D. candidate in Computer Science at the University of Auckland, advised by Dr. Meng-Fen Chiang, Prof. Kaiqi Zhao, and Prof. Sebastian Link.

I received my Master of Science (First Class Honours) degree in Computer Science from the University of Auckland in 2022, supervised by Dr. Meng-Fen Chiang and in collaboration with Assoc. Prof. Wang-Chien Lee of Pennsylvania State University. I completed my Bachelor of Science degree at the University of Auckland in 2019.

My research interests include:

• Knowledge Representation and Reasoning: Knowledge Graphs, Neuro-Symbolic Reasoning, Knowledge-Enhanced NLP
• Language Models: Retrieval-Augmented Generation, LLM Reasoning
• Multimodal AI: Multimodal Reasoning, Vision-Language Learning
