I graduated from Nottingham in 2002 and completed general medical training in Sheffield. During an Academic Clinical Fellowship in Sheffield I became interested in the host-pathogen interactions occurring during invasive bacterial infection with Streptococcus pneumoniae and Neisseria meningitidis. Between 2010 and 2014 I worked on the development of human challenge models of enteric fever (Salmonella Typhi and S. Paratyphi A) at the Oxford Vaccine Group (Oxford) and explored how these models relate to natural infection and how they might accelerate vaccine and diagnostic development. This work led to further studies of diagnostics, disease burden and vaccine implementation in endemic regions.
Antimicrobial resistance (AMR) is a major threat to global health and, for human-restricted pathogens such as S. Typhi, prevention by vaccination is a vital control strategy. After completion of specialist training and a Clinical Lectureship placement at the Oxford Clinical Research Unit in Ho Chi Minh City, Vietnam, I joined the Florey Institute for Host-Pathogen Interactions and IICD in 2018 as a Florey Advanced Fellow.
My research interests include:
- Investigating the drivers of antimicrobial resistance in lower- and middle-income country settings.
- Understanding the role and developing vaccines and diagnostics for enteric fever and other causes of non-specific febrile illness in low-resource settings.
- The ethical use of human challenge studies to advance the discovery and translation of tools for patient benefit.
I teach on the Diploma of Tropical Medicine and Hygiene (DTM&H) in Sheffield, the Diploma of Mountain Medicine in Nepal and Masters courses in molecular medicine and vaccinology. I am also involved in undergraduate and postgraduate teaching, demonstrating and supervision at the Medical School.
