BA (Hons) Biological Sciences (1st Class) – University of Oxford, 2012
My research focusses on sensory systems in invertebrates, with an emphasis on photoreception and vision in molluscs and echinoderms. Currently, I am studying a new photoreceptor in chitons, the Schwabe organ (see Sigwart et al. 2014, Sumner-Rooney and Sigwart in press). By using a combination of microscopic techniques, behavioural experiments, electrophysiology and molecular biology, one of my main aims is to discover the role of the Schwabe organ, and ultimately to learn more about its evolution and development. I have also been studying the structure and capabilities of the visual system of the brittle star Ophiocoma wendtii at the Smithsonian Tropical Research Institute in Panama. Again, anatomy and behaviour formed core parts of this project, alongside opsin sequencing, immunolabelling and comparative anatomy in order to discover what O. wendtii is capable of seeing, and how this ability might have evolved. Another key personal interest is the evolution of eye loss, which I have been investigating in a family of deep-sea gastropods in partnership with Dr Suzanne Williams at the Natural History Museum, London. My interests also include the architecture and evolution of nervous systems. I have recently contributed to a book on invertebrate nervous systems (see below) and have been awarded SYNTHESYS funding to digitise historic histological sections and use them to study variations in chiton neuroanatomy. Sensory systems have profound implications for many other aspects of the biology of these animals, influencing their evolution, ecology, and potential reactions to anthropogenic stresses, and yet they remain largely under-studied in non-arthropod invertebrate taxa.
