Guofeng Mei (梅国锋) currently serves as a researcher at Technologies of Vision (TeV), Fondazione Bruno Kessler, Italy. He works with Dr. Fabio Poiesi. He earned his Ph.D. in 2023 from the Faculty of Engineering and Information Technology at the University of Technology Sydney, Australia, supervised by Prof. Jian Zhang. Before this, between 2013 and 2016, Guofeng completed his Master's degree at the School of Mathematics and Statistics, Wuhan University, China, under the supervision of Prof. Xiaoqun Wu. In addition, Guofeng has had the opportunity to be a visiting scholar at the Multimedia and Human Understanding Group at the University of Trento, Italy, under the guidance of Prof. Nicu Sebe.

His research interests span optimization, computer vision, natural language processing, and machine learning. He particularly focuses on:

  • 3D vision-language models
  • Multimodal learning
  • 3D visual grounding
  • Point cloud registration
  • Graph matching
  • Image and video restoration
  • 3D instance segmentation
  • Embodied AI
