About Me

I am currently a first-year PhD student at inclusive NLP (iNLP) Lab (github) @ SUTD, led by Prof. Wenxuan Zhang. Prior to this, I completed my master’s degree supervised by Prof. Deyi Xiong, as well as my undergraduate studies under the guidance of Prof. Peifeng Li and Associate Researcher Feng Jiang.

My research focuses on linguistic, cultural, and multimodal diversity in Large Language Models (LLMs), advancing inclusive AI.
