In this book extra, I talk with clinical epidemiologist Dr. Salim Abdulla from the Ifakara Health Institute in Tanzania. Salim is an expert on malaria and has worked on studies of diagnostics, insecticide treated nets, drugs and vaccines, and field trials from Phase I to Phase IV. We talk about his early interest in malaria, his work on RTS,S, and his thoughts about international collaborations. To learn more about his work, check out @ifakarahealth on Twitter and read more in Global Health Research Methods.
