John Daugman is Professor of Computer Vision and Pattern Recognition at the University of Cambridge, Faculty of Computer Science and Technology. He carried out work in computational neuroscience and in computer vision for the development of wavelet methods for image coding and analysis, and invented the 2D Gabor wavelet-based iris recognition algorithm, which became the basis of all publicly deployed iris recognition systems. Daugman received his A.B. and Ph.D. degrees at Harvard University and then taught there for 5 years. After short appointments in Germany and in Japan he went to the University of Cambridge to research and teach computer vision, information theory, and statistical pattern recognition. He held the Johann Bernoulli Chair of Mathematics and Informatics at the University of Groningen in the Netherlands, and the Toshiba Endowed Chair at the Tokyo Institute of Technology in Japan.
