My current Postdoctoral Research position is due to end on 30th September 2025. I am keen to continue working in infectious disease research, data-driven epidemiology, and teaching in academia, public health, and/or industry. If you know of any opportunities, please do let me know - thank you!

I hope all my fellow #shigellaphiles have 20 - 24 April 2026 blocked out in their diaries for @shigellameeting.bsky.social next year in Paris! In the meantime, check out (and join) our starter pack to start community building now 🧫

Why did sexually transmissible shigellosis outbreak reporting re-emerge in the early 2000s? Below, our preprint explores the genomic epidemiology and temporal dating of Shigella sonnei from two early outbreaks in London & Berlin. 🛟🧪🧬🖥️🦠💉🧫😷https://www.medrxiv.org/content/10.1101/2025.05.02.25326874v1

The natural history of the emergence of sexually transmissible shigellosis

Shigellosis is a gastrointestinal illness caused by bacteria belonging to one of four species of Shigella . Sexually transmissible shigellosis was first reported in 1974, but recently there has been a...

Using demographics of patients to inform treatment of shigellosis in England

Shigellosis, caused by bacteria of the genus Shigella, is a diarrhoeal disease transmitted by the faecal–oral route.1 Rapid increases in the prevalence of extensively drug-resistant (XDR) Shigella iso...

Between 2009-2014, an epidemic of sexually transmissible Shigella flexneri 3a occurred in England that subsequently declined. However, from 2018-2021, S. flexneri 3a re-emerged. We explored possible drivers of the re-emergence by comparing host demographic features and pathogen genomics. 🛟🧪🧬🖥️🦠💉🧫😷
