BA (Hons) Biological Sciences (1st Class) – University of Oxford, 2012
My research focusses on sensory systems in deep-sea invertebrates. Currently, I am studying a novel sensory organ in chitons, the Schwabe organ (see Sigwart et al. 2014). By using a combination of microscopic techniques, electrophysiology, behavioural experiments 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 am also investigating the evolution of eye loss in a family of deep-sea gastropods in partnership with Dr Suzanne Williams at the Natural History Museum, London. During the remainder of my PhD I will also be studying other sensory systems in both molluscs and echinoderms, with an emphasis on photoreception and vision. I have recently contributed to a book on invertebrate nervous systems (see below) and in spring 2015 I will be taking up a short-term fellowship at the Smithsonian Tropical Research Institute in Panama to study photoreception in brittle stars. 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.
