I am a PhD student at Nanyang Technological University (NTU), Singapore, supervised by Prof. Ziwei Liu and Dr. Hongyuan Zhu.

Previously, I obtained my Bachelor's Degree from NTU, and I spent a wonderful time working with Prof. Ranjay Krishna at University of Washington on vision-language model reasoning, and Prof. Bihan Wen at NTU on low-light image enhancement.
