About the Project

NON-CLINICAL OPTION

Inflammatory bowel diseases (IBD) are chronic and debilitating conditions affecting over 5M people worldwide. They arise due a breakdown in the dialogue between the immune system and the intestinal microbiome, leading to aberrant inflammation. This project will examine the interaction between host genetics and the microbiome with a specific emphasis on barrier surfaces immunity. Genetic models will include those identified in Mendelian Diseases with IBD such as mutations in Syk (a kinase involved in immune cell function) as well as the recently described novel bacterial metabolite sensor Alpk1. The project will employ cutting edge mouse models of intestinal inflammation and immunological techniques alongside novel gnotobiology including rederivation of strains under germ-free conditions and study of humanized and novel synthetic microbial communities and their metabolites. The project seeks to identify how genetic predisposition drives intestinal inflammation through alteration in the functioning of the microbiome. 

TRAINING OPPORTUNITIES:

This project offers exposure to cutting edge technologies encompassing genomics, immunology, metabolism and microbiome sciences.
