My research area is visual computing, which includes computer graphics, computer vision, and multimedia. My goal is to develop technologies to support high-quality visual content production, provide convenient tools to visualize and interact with visual content,
and enable computational understanding of visual quality. Accordingly, my research effort has been devoted to three topics: computational photography and cinematography, computational aesthetics, and video visualization and interaction. Besides these topics, I am also exploring two new topics,
aggregation for visual computing and wearable visual sensing such as smart glasses and smart helmet that aim to provide a wearable platform for monitoring human activities and their interaction with the environment.
My research has resulted in over 80 publications in premier venues like SIGGRAPH, CVPR, ICCV, CHI, and IJCAI as well as prestigious awards, such as the best paper honorable mention awards at the prestigious ACM CHI and ACM Multimedia conferences, Google Faculty Research Award, and Intel Early-Career Faculty Honor Program Award. My research has also been transferred into commercial products and widely used in mainstream movies. To support my research, I have obtained about $2.5 million research support from NSF as well as companies like Google, Intel, Adobe, Samsung, Snap, Sharp, Nvidia, and Sony. |
