About Me

I am currently pursuing my Ph.D. at University College London (UCL). My research focuses on improving interactive pedestrian navigation through Computer Vision (CV) methods, with a particular emphasis on vision-based geolocalisation techniques. This work is funded by UK Research and Innovation (UKRI)/Engineering and Physical Sciences Research Council (EPSRC), in collaboration with Ordnance Survey (OS), and supported by the UCL International Scholar Doctoral Training Award (ISAD). The research is supervised by Prof. Jan Boehm (UCL), Dr. James Haworth (UCL), and Dr. Stefano Cavazzi (OS), and is part of the 3DIMPact and SpaceTimeLab research groups. In addition, I am a visiting student at the CV:HCI group at Karlsruhe Institute of Technology (KIT), supervised by Prof. Rainer Stiefelhagen (KIT), and Prof. Jiaming Zhang (HNU).
