I am a SAIL Postdoctoral Fellow working with Prof. Jiajun Wu, Prof. Fei-Fei Li, and Prof. Silvio Savarese at the Stanford Vision and Learning Lab. I received my Ph.D. at The University of Texas at Austin advised by Prof. Kristen Grauman, and my B.Eng. from The Chinese University of Hong Kong. My research interests are mainly in computer vision and machine learning. Particularly, I am interested in multisensory learning with sight, sound, and touch. My research goal is to teach machines to see, hear, and feel like humans to perceive, understand, and interact with the multisensory world.
