Gut microbes in health and disease


I completed my undergraduate degree (BSc Biomedical Science) at the University of Surrey in 2017.  During my placement year I worked at the Animal and Plant Health Agency, testing for antimicrobial resistance genes in animal faecal samples and developing a test to detect Escherichia coli in faeces.

I became interested in the human microbiome in disease throughout my degree and decided to continue in research afterwards, applying for a PhD at the University of East Anglia/Quadram Institute Bioscience.  My project is specifically looking at the gut microbiome in rheumatoid arthritis (RA), a chronic inflammatory disease of the joints.

I am particularly interested in associations between gut microbiome composition and treatment outcomes in RA (pharmacomicrobiomics) and intestinal permeability (leaky gut).
