I am a Professor of Visual Computing in the Department of Computer Science at University College London, where I am a member of the Virtual Environments and Computer Graphics Group. My research area is visual computing with a particular interest in real-time rendering, illumination computation, materials, perception, computational photography, and video-based rendering.

I have six doctoral students, Dan Calian, Daniyar Turmukhambetov, Yotam Doron (sponsored by The Foundry), Fabrizio Pece, Frederic Besse, and Fabian Wanner (sponsored by Framestore), who are working on 3d reconstruction, rendering, computational photography, and video-based rendering. Furthermore, I have two post-docs, Neill Campbell, who is working on synthesizing photo-real objects and Kartic Subr (Newton fellow), who is working on rendering and image processing.
