About

I am a final year Ph.D. student at University College London (UCL), working on Computer Vision methods for interactive pedestrian navigation, with a particular focus on vision-based geolocalisation. My research is funded by UKRI/EPSRC iCASE in collaboration with Ordnance Survey (OS) and supported by the UCL ISAD. I am supervised by Prof. Jan Boehm, Dr. James Haworth, and Dr. Stefano Cavazzi, and I am affiliated with the 3DIMPact and SpaceTimeLab groups. I was also a visiting student with CV:HCI at KIT, supervised by Prof. Rainer Stiefelhagen and Prof. Jiaming Zhang.

I'm open to potential postdoctoral positions or industry internships in visual localisation.
