My Work

Our group works to understand the interaction between helminth parasites and the gut microbiota, and on how both of these input into the gastro-intestinal ecoystem in health and disease. We use next-gen sequencing approaches and muli-omics to develop novel diagnostic and therapeutic strategies for veterinary species, and use a One Health approach to understand the pathophysiology, across species, of diseases such as obesity, inflammatory bowel disease and chronic inflammation. In addition, we work to understand how parasitic helminths stimulate and regulate the host immune response. We also have science outreach and citizen science projects building on our One Health approach

Potential Projects

Our group would welcome students interested in projects in the following areas, which all involve collaborations between basic scientists and veterinary clinicians, and will allow candidates to develop skills in such areas as bio-informatics, molecular parasitology, one health, and parasite immunology

Characterisation of the gut microbiota response of obese and overweiight dogs to diet and exercise
Exploration of the similarity and differences between the gut microbiota of dogs and their owners (dog owner microbiome study)
Development of personalised diagnostics and therapeutics for equine gastro-intestinal diseases
Introduction of "nemabiome" approaches into the diagnostic parasitology laboratory and related applications
Understanding the equine immune response to cyathostomin infection
