John Andrew Crump
Adjunct Professor in the Department of Medicine

I am based in northern Tanzania where I am Site Leader for Duke University’s collaborative research program based at Kilimanjaro Christian Medical Centre and Director of Tanzania Operations for the Duke Global Health Institute. I oversee the design and implementation of research studies on infectious diseases, particularly febrile illness, invasive bacterial disease, HIV-associated opportunistic infections, clinical trials of antiretroviral therapy and prevention of mother-to-child transmission of HIV, and infectious diseases diagnostics. In addition, I am a medical epidemiologist with the US Centers for Disease Control and Prevention (CDC). My CDC work focuses on enteric infection epidemiology and prevention in developing countries, particularly invasive salmonelloses.
