I'm a PhD student at University of California San Diego, advised by Prof. Xiaolong Wang. I received my Master's and Bachelor's degrees in computer science from National Tsing Hua University. Recently, I'm honored with the Qualcomm Innovation Fellowship.

My research focuses on 3D Vision. I’m interested in how we can enable machines to better understand the physical world through self-supervised methods.
