Thomas Bashford-Rogers

Institution: The University of Warwick
Position: Associate Professor
Research: My research focuses on realistic and accurate Computer Graphics, and I'm especially interested in how to efficiently simulate light transport in realistic and detailed virtual environments. This involves developing novel light transport simulations, importance sampling, and MCMC. I also work in other areas such as AI and Deep Learning, HDR imaging, exploiting human perception for computational gains, and cross-disciplinary research with other domains.
Education: Completed my PhD at Warwick with a thesis titled "Accelerating Global Illumination for Physically-Based Rendering", and before that did my undergraduate degree in Computer Science in Bristol University. I am also a FHEA.
Teaching: Program Lead for MSc Games Engineering at the University of Warwick. Formerly was a Senior Lecturer in Games Technology at UWE Bristol.
