University of Bristol VI Laboratory


I am a third-year PhD student in the Visual Information (VI) Laboratory at the University of Bristol, supervised by Dr. Angeliki Katsenou and Prof. David Bull, and funded by the UKRI MyWorld Strength in Places Programme.

My main research interests include video quality assessment and computer vision. I am particularly interested in topics such as content delivery, interactivity, and audience understanding, with a primary focus on video quality assessment for user-generated content (UGC).
