Evidence-synthesis tools, courses, and methods atlases — built with and for clinicians and students in the Global South.

Cardiology specialist at the Royal Free Hospital, London, with a research home at the Tahir Heart Institute. I build evidence-synthesis tools, run a weekly micro-paper course at Makerere, and lead methods atlases on prediction-interval calibration, reproduction floors, and African representation in Cochrane reviews.
