I am a PhD student at ETH Zurich and University of Tübingen, supervised by Marc Pollefeys and Andreas Geiger. I was very fortunate to work with several amazing supervisors. I spent a wonderful time working remotely with Jianfei Cai and Hamid Rezatofighi at Monash University, Australia, prior to starting my PhD. I obtained a master's degree at University of Science and Technology of China (USTC) supervised by Juyong Zhang. During my master's, I exchanged at Nanyang Technological University (NTU), Singapore, where I was supervised by Jianfei Cai and Jianmin Zheng. I also interned at Microsoft Research Asia (MSRA), where I was mentored by Jiaolong Yang and Xin Tong. |

I have broad interests in computer vision, particularly in fundamental research problems like dense correspondences, motion, 3D and video representation learning. I like to explore simple and effective approaches to solving fundamental challenges. Please see the full publication list on Google Scholar. |
