About

I am an Associate Professor in the School of Computer Science at the University of Bristol (UoB) and a member of the Visual Information Laboratory, led by Prof. Alin Achim, and the Bristol Vision Institute, led by Prof. David Bull. I have been involved in many projects across multiple disciplines, including telecommunications, biology, optometry, clinical sciences, biochemistry, mechanical engineering, psychology and geoscience. I lead a work package, AI Workflows for Challenging Acquisition Environments, as part of MyWorld, strengthening the world-leading position of creative technologies in the southwest region. Additionally, I am a key scientist at the Centre for the Observation and Modelling of Earthquakes, Volcanoes, and Tectonics (COMET).

I am a Programme Director of MSc Immersive Technologies (Virtual and Augmented Reality). During the 2024/2025 academic year, I will be on a University Research Fellowship and therefore will not be involved in teaching. For any inquiries regarding Image Processing and Computer Vision (Y3), Advanced Visual AI (Y4), and Immersive Interaction and Audio Design (PGT), please contact the respective Unit Directors.
