About Me
Hi! I am an AI Researcher at the Singapore Search & Recommendation Lab, Huawei. Previously, I completed my Ph.D. through a joint programme between Alibaba DAMO Academy and Nanyang Technological University, Singapore, under the supervision of Prof. Luu Anh Tuan. Throughout my PhD, I had the pleasure of working closely with Dr. Wenxuan Zhang and Dr. Lidong Bing. Prior to that, I received both my Master of Engineering and Bachelor of Engineering degrees with First Class Honours from Nanyang Technological University, Singapore.
My research interests include Agentic Systems, Multimodal Embedding, Low-resource Natural Language Processing, Multilingual and Multimodal Large Language Models.
