I am a fifth-year PhD candidate in the Vision Science Program at University of California, Berkeley co-advised by Prof. Stella Yu and Prof. David Whitney. Before joining UC Berkeley, I received my Master's Degree in Electrical and Computer Engineering at University of California, San Diego, co-advised by Prof. Nuno Vasconcelos and Prof. Bhaskar D. Rao. I received my Bachelor's Degree at University of Electronic Science and Technology of China (UESTC) and Bachelor's Degree with Honours at University of Glasgow, advised by Prof. Shuaicheng Liu. My research interests include: image and video processing, computer vision, and applications on medical imaging. I am also highly interested in human vision system.

    Interests

    Coming from Chengdu where sunny days are precious, I appreciate every moment in the California sunshine. I love traveling, photography, and anything which could drag me outdoors. In particular, I like star shooting and wildlife shooting. You could find some of those photos in my instagram.

    When forced indoors, I follow a number of sci-fi and fantasy genre movies and television shows. I also love cooking. Sharing spicy and hot Sichuan food with friends is my favorite.
