Mark is a leading psychologist and Head of the School of Psychology at the University of Leicester. Mark read Natural Sciences at Trinity College Cambridge; specialising in experimental psychology. After spending time there as a research student and doctoral research fellow, he worked for ITT researching into how the environment in which we work dictates the way we think. This led in the 1990s to a controversial idea that messy desks might actually be highly effective for certain types of workers because it is well-adapted to the way our minds work. This was followed by spells at Loughborough and Nottingham Trent Universities before becoming Head of Leicester's School of Psychology in 2008. Current research continues in the area of how people think and remember as a function of their environment. This has led to research interested in historical figures in unusual circumstances – such as Monarchs, and generals in world wars – to see how much psychologists can inform historical analysis.
