I run Abertay’s Visual Perception and Camouflage Lab which is concerned with the processes underlying visual perception and with the ways in which camouflage undermines these processes.
Our research uses a range of techniques, ranging from visual psychophysics to virtual reality, video games and sometimes behavioural studies with animals.
I’ve been involved in various Knowledge Exchange Projects including developing baseline visibility measures of signs and signals for Network Rail.
I’ve published extensively within the area of visual perception including studies on visual impairment in dementia and camouflage in nature (for example, exploring whether quail choose to lay their eggs in locations that help to camouflage their eggs).
I’ve been interviewed on various media outlets including national radio and newspapers to discuss camouflage in nature.
I am a peer reviewer for Perception, Vision Research, Journal of Vision, Behavioural Ecology and Sociobiology.
I’m also a member of the Vision Sciences Society and the Applied Vision Association.

October 2012. Researcher/Co-investigator, (PI Julie Harris). Grant total £401k (across all sites). From photons to fitness. Using calibrated photogrammetry to ask whether countershading in animals is really optimised for camouflage. In this collaboration with renowned experts in animal camouflage (Graeme Ruxton, Glasgow and Innes Cuthill Bristol). We will examine the long standing question of whether counter-shading pigmentation really does hide animals by concealing their shading cues. (£401,000). The project will accurately render 3D models of organisms under simulated natural light environments. We can then examine whether counter-shading aids concealment using visual search tasks in humans and starlings. (BBSRC BB/J000272/1)
