Overview
I am an Adjunct Professor of Medicine, Pathology, and Global Health. My work with Duke University is primarily based in northern Tanzania where I am former Site Leader and current Principal Investigator on projects linked to Duke University’s collaborative research program at Kilimanjaro Christian Medical Centre. I oversee the design and implementation of research studies on infectious diseases, particularly febrile illness, invasive bacterial disease, zoonotic infections, and infectious diseases diagnostics. In addition, I am Professor of Medicine, Pathology, and Global Health at the University of Otago and a medical epidemiologist with the US Centers for Disease Control and Prevention (CDC). My CDC work focuses on non-malaria febrile illness.
