About

I am currently a PhD student (Oct 2022 - Present) at the Visual Information Laboratory, University of Bristol. My research is supervised by Prof. David Bull and Dr. Aaron Zhang. My research is funded by EPSRC (iCASE), BT, and the UKRI MyWorld Strength in Places Programme. My research interests include deep video compression and volumetric video compression, particularly based on neural representations.
