I am a Lecturer at the University of Essex. Previously, I have worked at the University of Exeter and University College London. I completed my PhD at the University of Cambridge with David Tolhurst and Martin Stevens.
Please feel free to get in touch to find out more about the work done in the lab or opportunities to take part in our research.
I am interested in how humans and other animals perceive the world and how they use this information to make decisions.
My PhD research was on how camouflage patterns interfere with motion perception, and in particular whether certain types of high contrast patterning (such as stripes or zigzags) can affect speed or direction perception. This idea has been termed ‘motion dazzle’ and it has been hypothesised that it may explain some of the striking patterning seen in many animals, including zebras and many snakes, fish and insects.
In collaboration with Dr Laura Kelley and Foam Kernow, I have been involved in setting up The Dazzle Bug Game, an online citizen science game aimed at finding out what makes a moving target difficult to catch.
During my postdoc in the Sensory Ecology group, I carried out work looking at how camouflage should be optimised when an animal can be viewed on multiple different habitats - should it specialise to match one particular background, or should it evolve a form of generalist, compromise camouflage that offers imperfect protection on multiple backgrounds?
In collaboration with colleagues at the Czech Institute of Vertebrate Biology, we have been working on questions about the visual ecology of avian obligate brood parasites (common cuckoos) and their hosts and conspecific brood parasites (barn swallows). Questions we are interested in include whether hosts can recognise foreign eggs, how good parasitic egg mimicry is and whether egg appearance can act as a 'fingerprint' to identify an individual.

I have also been known to teach (both to students and the wider public!) about visual perception, sensory ecology and experimental design in psychology.
