His research, for which he was based in Kenya, has included trials assessing: (i) the risk of malaria infection following iron supplementation in pregnancy, (ii) safety and efficacy of primaquine as a gametocidal drug in children with malaria, and (iii) high-dose ivermectin as a first-in-class mosquitocidal drug. Currently he is involved as an investigator and DSMB member in several trials across the globe that are assessing the use of ivermectin for the elimination of malaria and neglected tropical diseases.
