About Me
I am an associate professor at the at the School of Computer Science and Engineering, Sun Yat-sen University (SYSU), where I work in HCP Lab (Human-Cyber-Physical Intelligence Integration Lab) supervised by Prof. Liang Lin. Before that, I received the Ph.D in Computer Science from University of the Chinese Academy of Sciences in 2018, advised by Prof. Jianbin Jiao and Prof. Qixiang Ye. I obtained the B.Eng. from China University of Mining and Technology, Beijing, advised by Prof. Feng Yang.
Research interest: My general research interest is Towards Transferable, Robust and Reliable Model Learning for computer vision tasks. Recently, I specifically focus on

Real-World Image Super-Resolution Challenge (AIM 2020 in conjunction with ECCV 2020) [AIM2020 webpage]
We provide high/low resolution image pairs of 3 scales captured by 5 different DSLR cameras through zooming lens. The challenging contains 3 tracks, one track per scale. The detail of the dataset is provided in Table 1. For the convergence of training, images in the trainset are cropped into fixed size patches using sliding window after careful alignment for image pairs. [Chanllenge Page]

IEEE CASS Seasonal School on New Trends of Visual and Language Understanding (NT-VLU) [Website, Video]
To organize the IEEE CASS Seasonal School on NT-VLU, we invited several top-tier researchers to present their works and arrange two panels to discuss the new trends of NT-VLU. This seasonal school aimed to promote the frontier of language and vision research and to provide an ambiance for fruitful exchange of ideas and discussion of advances, challenges, and trends of this area in the near future.
