I joined the KEMRI-Wellcome Trust Research Programme in 1998 as a junior doctor and was interested in training in paediatrics. It was here that I was introduced to research on malaria in general, and begun to understand that we know so little about this disease that has been with humans for such a long time.

The closest comparison I can give is with COVID-19. When it hit Western countries, we all felt it: the pain of lockdown; of losing someone; of being ill ourselves. We felt that urgency, that we needed a vaccine and we needed it yesterday, so we said, ‘let's do it, let's do everything that we can’. For diseases that are far off, that sense of urgency is lost.

My average day has evolved over the years as I have graduated from being a junior to a more senior researcher. Earlier on, I’d spend a lot of time in the laboratory generating data and less time in the office reading scientific literature, analysing data and writing up my work.
