I am a postdoctoral researcher working on visual signalling and anti-predator strategies, with a special interest in visual communication in Lepidoptera. In my current role in Martin Stevens’ Sensory Ecology and Evolution lab, I am investigating the relative benefits of specialist and generalist strategies for background-matching camouflage, using a mix of field experiments and online search games.

My previous research has covered a range of topics in animal coloration, from cuttlefish camouflage patterns to the functions of zebra stripes, but my main projects have focused on colour patterns and visual perception in Lepidoptera. For my PhD, I investigated warning coloration in day-flying burnet moths (Zygaenidae), relating variation in colour pattern, chemical defence levels and predation risk, both within and between species, to test signal honesty in this system. Recent projects include work on the effects of conspicuous wing patterns on predator perception during butterfly flight, and visual modelling of how artificial lighting might affect colour perception by nocturnal hawkmoths. I am especially interested in using an understanding of visual ecology to approach problems relevant to biodiversity conservation, and enjoy raising awareness of the extraordinary adaptations of vulnerable species through public engagement, including outreach events and a children’s book exploring the visual defences of moths.
