Gastrointestinal dwelling nematode parasites are extremely successful parasites of both man and animals infecting over a billion people worldwide and are responsible for considerable morbidity and ill health worldwide. Of these whipworm (Trichuris trichiura) infects around 1 in 15 of the world population. Our laboratory has been at the forefront of research into whipworms using the natural mouse model Trichuris muris. Despite our detailed understanding of the host immune response to T. muris infection, our basic understanding of the biology and morphology of the parasite is extremely poor at the ultrastructural level. As parasites that have adapted to living in the intestinal epithelium, a detailed understanding of the anatomical relationship of the parasite to the host and a spatiotemporal analysis of important genes that they express will be key to moving the field forward. The project will build on the work we carried out defining the genome of Trichuris and involve scanning, transmission and 3D electron microscopy together with immunoelectron microscopy, light microscopy and gene analysis. The project will utilise state of the art equipment and infrastructure in our imaging core facilities. The student will be embedded within a well-funded group studying parasites and immunity, part of the Lydia Becker Institute of Immunology and Inflammation and the Wellcome Centre for Cell Matrix Research.
The project will involve scanning, transmission and 3D electron microscopy together with immunoelectron microscopy, light microscopy and gene analysis. In addition, skills in parasitology will be gained including maintenance of parasite life cycles and experimental animal work.
Candidates are expected to hold (or be about to obtain) a minimum upper second class honours degree (or equivalent) in a biologically related area. Candidates with experience in parasitology , imaging and/ or with an interest in electron microscopy are encouraged to apply.
For international students we also offer a unique 4 year PhD programme that gives you the opportunity to undertake an accredited Teaching Certificate whilst carrying out an independent research project across a range of biological, medical and health sciences.
