Andy is leader of the computer graphics research group. He established the Urban Modelling Group (UMG - www.urbanmodellinggroup.co.uk) and the Crowd Simulation Group (CSG - www.crowdsimulationgroup.co.uk). He has published over 100 research papers and holds (or has held) several EU and EPSRC grants. His research interests are in applied computational geometry, real time rendering and behaviour of crowds and haptics for deformable bodies. UMG works closely with the School of History (Virtual Past) on virtual historic reconstruction.
He has worked as an engineer for BT, as a school teacher of Mathematics and as a FE lecturer in Mathematics and Computing at Norwich City College. At UEA he was appointed Lecturer in Computing Science in 1985. In 1999 he became a Senior Lecturer and in 2003 was promoted to Reader in the School of Computing Sciences. In 2005 he was appointed to Professor of Computing Science. He is a fellow of Eurographics.
Andy has a First class degree in Mathematics from UEA and in 1990 he was awarded a PhD in Computing Science, 'The Serial and Parallel Implementation of Geometric Algorithms', at UEA.

Key Research Interests
Andy Day is leader of the Computer Graphics Group
His main research interests are in the application of computational geometry to computer graphics, haptics, crowd and urban visualisation and virtual environments.
He began research in 1985 with the Computational Geometry Group, headed by Prof. A.R. Forrest, on the serial and parallel implementation of geometric algorithms. His early work concentrated on the problems of degeneracy in geometric algorithms for convex hulls and Voronoi diagrams. He has also worked on scientific visualisation of environmental data with the School of Environmental Sciences at UEA. He has researched parallel high performance image synthesis using ray tracing techniques and fast methods of space partitioning using BSP trees and pre-processing for interactive walkthroughs. He was co-investigator with Prof. D B. Arnold on the EC project ETHOS in 1999, to identify, demonstrate, and evaluate Generic Technologies for Virtual Environments. He was also co-investigator on the EC CHARISMATIC project (Cultural Heritage Attractions featuring Interactive Scenes and Multi-function Avatars as Theatrical Intelligent Characters) in 2000. On this project the UEA group researched rapid modelling using procedural methods and rendering acceleration techniques for populated urban scenes. He was principal investigator on the EPSRC (Engineering and Physical Sciences Research Council) Rapid World Modelling project (2000) which focused on modelling the planet earth using compression techniques and the automatic modelling of urban environments. He currently holds three EPSRC grants for Real Time Crowd Rendering and Urban Modelling for Transport Studies.
He has also researched haptic rendering and virtual environments since 2001 and his recent work with Dr. S. Laycock on deformable tools, such as bending rods, has important applications in medical training (such a steerable catheter simulation), engineering and virtual prototyping.
