Biographical details

I'm an evolutionary biologist with a particular interest in questions of adaptive evolution, behaviour, and sensory ecology. Our research in the Evolutionary and Sensory Ecology Lab is motivated by a desire to understand life’s diversity, and we use experimental, observational, and mathematical tools to test and extend theory. Invertebrates have proven a particular source of inspiration, with butterflies, spiders, and flies being mainstays in the lab, though we gladly use any system useful for the questions at hand.

Research interests

Our current research is broadly centred on three themes:

  1. The evolutionary ecology of visual communication. Visual communication is ubiquitous in nature. It underlies some of the most conspicuous aspects of biological diversity—such as the colours of animals and plants—and we are interested in understanding the mechanisms, causes, and consequences of this mode of information exchange. Current projects focus on examining how suites of signalling traits coevolve to enable the effective exchange of information in 'noisy', real-world conditions, and how the information encoded in diverse visual cues (e.g. colour, pattern, motion) is integrated and weighed by viewers to ultimately affect behaviour. To that end, we also enjoy testing and extending quantitative methods for analysing colour and vision in nature, as well as developing open software that improves the accessibility of such tools.
  2. Natural and sexual selection in the wild. How are intersexual differences reconciled with the fact that males and females largely share a genome? Can we predict the trajectory of evolution? How does social and natural selection interact to shape local adaptation? We are keen to understand the workings of adaptive evolution in nature. Current projects span sexual selection, reproductive isolation, and local adaptation in beach-dwelling flies, the consequences of cognitive biases for sexual and deceptive signal evolution, and using urban environments as novel testing grounds for theory.
  3. The evolution and maintenance of extreme variation. Species that exhibit dramatic phenotypic variation—such as colour polymorphism and sexual dimorphism—offer exciting opportunities for studying the fundamental evolutionary processes that generate diversity. We have a long-standing interest in these extremes, such as the colour polymorphic lures of trpoical spiders and the sexually dimorphic ornaments of flies. We are still working to unravel those particular puzzles, and have ongoing projects centred on understanding the evolution of dimorphism and polyphenism using model butterflies.
