Alistair Benford

University of Edinburgh, School of Informatics

I am currently a research associate at the University of Edinburgh where I am working with Heng Guo. My research interests include randomised algorithms, competitive coevolution, mathematical foundations of machine learning, game theory, and graph theory. Until recently I was a postdoc of Per Kristian Lehre at the University of Birmingham, and prior to this I undertook a PhD as part of Birmingham's Combinatorics, Probability and Algorithms group where I was a student of Richard Montgomery. Between 2015 and 2019 I completed an MMath at the University of Cambridge.
