Sarah Duxbury
PhD student


I completed my undergraduate degree in Biology, which included a broad range of fascinating topics, from cancer and developmental biology, neurosciences and infectious diseases to ecological concepts and theories of evolution. During my second and third years I particularly enjoyed studying infection and immunity combined with evolutionary biology. For my final year project, I studied a link between diet and immunity in the fruit fly Drosophila melanogaster, under infection by the fungus Metarhizium robertsii.

I have also carried out an undergraduate summer research project at The Sainsbury Laboratory in Norwich, where I studied the effects of biotic and abiotic stress on stomatal closure in Arabidopsis thaliana.

My current research interests lie in microbial ecology and evolution and I am particularly interested in the human microbiome (the natural communities of microorganisms colonising various sites within the body) and the variation in its composition, for example during disease. My PhD project supervised by Dr. Ivana Gudelj and Professor Ken Haynes focuses on the ecology of mixed species infections of Candida, an opportunistic fungal pathogen of humans, and evolution of antifungal drug resistance.

Broad research specialisms:

  • Microbial ecology and evolution
  • Systems biology of drug resistance
  • Fungal biology
