Visual AI Lab (VAIL) is a research group directed by Dr. Kai Han, working on computer vision, machine learning, and artificial intelligence, under Department of Statistics and Actuarial Science, The University of Hong Kong. The overarching goal of our research is to achieve principled and comprehensive visual understanding, close the intelligence gap between machines and humans, and build reliable AI systems for open-world use. Our current research focuses on open-world learning, 3D vision, generative AI, foundation models and their relevant fields.

🚩 Openings:
(1) PhD students: We are always looking for strong students to work on exciting research problems (☞ fellowships and scholarships).
(2) Postdocs: Positions in computer vision and deep learning are available, with a competitive salary.
Please drop Dr. Kai Han an email with your resume if you are interested in working with us.
