About Me

I am a first-year PhD student in EECS at UC Merced under the advisement of Prof. Ming-Hsuan Yang. Before coming to UC Merced in 2015, I studied at National Taiwan University, working with Prof. Yung-Yu Chuang and Dr. Yen-Yu Lin.

My research interests include Computer Vision, Computational Photography and Machine Learning. Here is my CV.


  • 08/2015: Start my PhD at UC Merced, California
  • 03/2015: One paper is accepted in CVPR 2015
