Currently, I am a postdoctoral scholar in Computer Vision Laboratory at ETH Zurich, working with Prof. Ender Konukoglu. Before that, I was a researcher at Inception Institute of Artificial Intelligence, Abu Dhabi, UAE. I got my Ph.D. degree from Beijing Laboratory of Intelligent Information Technology, Beijing Institute of Technology in 2017, under the supervision of Prof. Yao Lu.
