About

I am a PhD student at Purdue University, advised by Prof. Raymond A. Yeh. My research is in computer vision and machine learning, with a current focus on post-training adaptation methods and vision-language understanding.

I am fortunate to have interned at NVIDIA Research (2025) and MERL (2024). I received my Bachelor's and Master's degrees from National Taiwan University, advised by Prof. Yung-Yu Chuang, and subsequently worked as a Research Assistant in VLLab with Prof. Yu-Chiang Frank Wang.
