Project description

Coccidiosis, an enteric disease caused by Eimeria parasites, is a major threat to food security in poultry production, where it costs ~3 billion USD per year. A group of specialized secretory organelles including the micronemes and rhoptries drive the invasion and intracellular survival of these parasites. Parasite life cycle stages that contain these organelles induce strong protective immunity in the chicken host, so they are of considerable interest for the development of novel vaccines against coccidiosis. However, despite extensive community efforts, there are still 68% of proteins annotated as hypothetical in Eimeria tenella, one of the best-curated Eimeria species, with limited information on function and subcellular localisation. This lack of annotation has restricted the search for additional valid recombinant vaccine candidates.

This project aims to characterise the localisation of organelle proteins using advanced spatial proteomics approaches followed by machine learning based classification solutions. A number of novel protein candidates will be fused with fluorescent reporters to validate localisation and feedback to a bioinformatics pipeline to iteratively improve the prediction and classification accuracy. Data generated will be subsequently integrated with a multi-omics proteogenomic pipeline to further refine gene model predictions in collaboration with EuPathDB team. Functional annotation and domain structure of novel organelle proteins identified will be examined to identify new targets for disease intervention.

This is an exciting opportunity for an individual to join a multi-disciplinary project based at the UK's oldest and largest veterinary school and the London School of Hygiene and Tropical Medicine. The successful candidate will have the opportunity to develop skills in microbiology, molecular biology, cutting edge systems biology technologies in a high impact scientific field.

Extensive training and support will be provided on laboratory techniques and data analysis skills. A candidate should have a good first degree in a relevant subject. An MSc would be an advantage, as would experience of practical parasitology, and molecular biology.
