James Watson joined IDDO in March 2023 as Associate Director.
He is a Sir Henry Dale Fellow funded by the Wellcome Trust working on improving the diagnosis and treatment of severe falciparum malaria.
James is a statistician by training and previously worked at the Mahidol Oxford Tropical Medicine Research Unit in Bangkok for seven years before moving to the Oxford University Clinical Research Unit in Viet Nam.
His research interests also include the radical cure of Plasmodium vivax malaria, SARS-CoV-2 antivirals, Chagas disease, snakebite and adaptive trial design.
