Dr Alasdair Clarke



Alasdair Clarke has a background in mathematics (M.Math, University of Warwick) and a PhD in Computer Science (Heriot-Watt University). After his Phd, he worked as a post-doc at the School of Informatics, University of Edinburgh, and then at the School of Psychology, University of Aberdeen. His current research interests cover visual perception, search, and decision making.
