Chuofan Ma (马逴凡)

I'm a Ph.D. student from CVMI Lab, The University of Hong Kong (HKU), under the supervision of Prof. Xiaojuan Qi. Before that, I obtained my bachelor degree in computer science from HKU.

My research interest primarily lies in open-world visual intelligence and multi-modal foundation models. Please feel free to drop me an email if you are interested in what I do and seek for possible collaborations.
