Research summary

My research combines a range of techniques to study the function and evolution of sensory and nervous systems in invertebrates. These systems are staggeringly diverse, and they form the interface between organisms and their environment, having profound behavioural, ecological and evolutionary impacts. Currently, I’m focussing on the parallel changes to eyes and brains in animals inhabiting different light environments, from eagle-eyed hunters to blind cave species. Another main interest is how organisms without eyes navigate using light information. Through high-resolution microscopy and tomography, comparative morphology, behavioural experiments, transcriptomics and developmental biology, we can disentangle how and why these complex structures evolved, and what they can reveal about the history of animal life.
