I am a Lecturer (Assistant Professor) affiliated with the Vision, Learning, and Control (VLC) group in the School of Electronics and Computer Science (ECS) at the University of Southampton.
I specialize in computer vision and machine learning in the context of artificial general intelligence. My research focuses on improving machine learning by understanding human learning processes and exploring how AI can support and enhance both human life and the physical world. Central to our research team’s mission is the development of happy and green AI—artificial intelligence that is emotionally aligned, human-centered, and environmentally sustainable. Our work advances artificial machine intelligence with generative capabilities in perception, emotion, and action across computers, devices, and robots, with applications spanning healthcare, the arts, and education.

02/2025, One inspiring paper "OpenSDI: Spotting Diffusion-Generated Images in the Open World" has been accepted to CVPR 2025. Huge thanks to the reviewers and the chairs! Let's spot AI images, like those on social media (reported by BBC) , in the open world!
10/2023, We have openings for PhD positions: 'Generative Modeling in Computer Vision' and 'Deepfake Detection with Continual Learning'. Note that these positions are open to students from UK and Horizon Europe qualifying countries (meeting the criteria for UK home-level fees) as well as other international students.
02/2023, We are opening some positions for talents who are keen to publish papers, open source code, and make an impact.
02/2023, One interesting paper "Freestyle Layout-to-Image Synthesis" is accepted as a highlight (10% of accepted papers, 2.5% of submissions) to CVPR 2023. This paper introduces freestyle layout-to-image synthesis with diffusion generative network (FreestyleNet). The proposed FreestyleNet produces realistic-looking and creative images like ‘a warehouse running on a railroad’ and 'a hornless unicorn sitting on a bench'. Thanks all the reviewers for valuable comments and constructive suggestions!
01/2023, I join University of Southampton as a Lecturer (Assistant Professor) in Computer Science.
11/2022, One paper "An Efficient Recurrent Adversarial Framework for Unsupervised Real-Time Video Enhancement" gets accepted to IJCV.
11/2022, Two papers "Isolation and Impartial Aggregation: A Paradigm of Incremental Learning without Interference" and "Riemannian Local Mechanism for SPD Neural Networks" are accepted at AAAI 2023.

09/2022, One inspiring paper "S-Prompts Learning with Pre-trained Transformers: An Occam's Razor for Domain Incremental Learning" gets accepted to NeurIPS 2022. This paper proposes a rule-breaking continual learning paradigm (S-Prompts). It does not require the accumulation of the knowledge from previously learned domains. Instead, it merely learns the knowledge independently domain by domain, through simply prompting the state-of-the-art transformers.
