I am a trained immunologist and vaccinologist having undertaken DPhil on malaria transmission-blocking vaccines at the University of Oxford. Following on from this, I served as a post-doc with Kevin Marsh and Philip Bejon at the KEMRI-Wellcome Trust Research Programme in Kilifi working on assessing the infectious reservoir of malaria. From 2015, portfolio of work expanded to setting up currently the largest single-site falciparum controlled human malaria infection study in 161 volunteers leading a diverse team in Kenya in collaboration with key partners in this field.
