Bacterial niche adaptation

My research interests focus on narrowing the gaps between scientific disciplines (chemistry, biology, physics, medicine, etc) to develop innovative methods that tackle the big modern scientific challenges. Following my chemistry undergraduate, I undertook a biochemistry/photochemistry PhD at the University of East Anglia (UEA) where I developed methods for producing photosensitiser-proteoliposome systems to study light driven transmembrane electron transfers via a porin:cytochrome protein complex. Following this I worked on heme enhancement systems for overexpression within cytochromes in E. coli.

I joined the Norwich Medical School at UEA in early 2017 to help generate transposon libraries of non-aureus staphylococci for transposon-directed insertion sequencing (TraDIS). These libraries, used with developed biofilm models, have helped to identify essential genes required for biofilm formation that lead to prosthetic joint infections. I have developed this biofilm model to investigate both the application of bacteriophage technology to treat staphylococcal prosthetic joint infections and the essential genes required for initial biofilm formation of P. aeruginosa.

I joined the Quadram Institute in late 2018 where I have been investigating the molecular mechanisms used by Salmonella Typhi to survive in an asymptomatic state in humans – known as the carrier state. I use genomics techniques such as long-read sequencing and TraDIS to determine if S. Typhi samples have undergone large-scale genome rearrangements and which genes are essential for biofilm formation, respectively.
