I have been with the Department of Computer Science at the University of York since July 1991. I am currently Professor of Computer Vision, having previously been Lecturer, Senior Lecturer and Reader. My research interests are in the areas of computer vision and pattern recognition. I have externally funded projects in the areas of terrain analysis, sensor fusion and visual learning. Funding for my activities here has totalled more than GBP 2M over the past five years. Most of what I do involves Bayesian models or optimisation. An important thread running through my research is how to use relational graphs to represent visual information and how to match inexact graphs. Ongoing research topics include machine learning in computer vision, graph-spectral methods, 3D surface reconstruction from 2D images and quantum computing. I am happy to supervise research-students in the broad areas of computer vision, statistical pattern recognition or connectionism.
