I am a PhD student at the University of Liège in Belgium, funded by the FNRS. I work under the supervision of Prof. Marc Van Droogenbroeck, Dr. Anthony Cioppa, and Dr. Silvio Giancola. My research interests include 3D understanding and novel view synthesis. Currently, I am a visiting student at the Image and Video Understanding Laboratory (IVUL) within the Center of Excellence for Generative AI at KAUST, where I am advised by Prof. Bernard Ghanem.

As a football referee, I am also interested in automatic video analysis and understanding in sports. Additionally, we organize international challenges focused on AI applications in sports.

For any questions, please feel free to email me at jan[dot]held@uliege.be
