Research Interests

The immunopathogenesis and neuropathogenesis of infectious diseases.

I work within a group that aims to understand the pathogenesis of infectious diseases within the immune system. Particular interests include understanding host-pathogen interactions within the mucosal immune system, especially prion diseases and other gastrointestinal pathogens such as Salmonella and nematodes. Studies are also focused on the effects of host age on the function of the immune system and how this influences susceptibility to gastrointestinal pathogens.

Current Research Interests

Prion Disease (transmissible spongiform encephalopathies):

  • The role of the immune system in peripheral prion pathogenesis 
  • Glial responses and prion neuropathogenesis
  • Prion strain typing using molecular markers
  • Neurobehavioural outcomes during prion infection

B-cell follicle homing chemokine CXCR5, application of conditional CXCR5fl mice to immune system function

  • Dendritic cells and Th2 responses


Following completion my BSc with Neuroscience (Hons), I joined the Institute for Animal Health Neuropathogenesis Unit (IAH-NPU) Edinburgh, UK in 2000. Initially working within the Mouse Genetics Group on transgenic mouse models of conditional prion gene expression and prion protein glycosylation mutant models.

I have over 18 years of experience studying the neuropathology and immunopathogenesis of transmissible spongiform encephalopathy (prion disease) as well as other models of infectious disease and parasitic infections.

I am currently employed as a Post Doctoral Research Scientist within the Mucosal Host Pathogen Interactions & Prion Research and Neuropathology Groups as well as managing the Histology Facility at The Roslin Institute & Royal (Dick) School of Veterinary Sciences, The University of Edinburgh, Edinburgh, UK
