Curriculum Vitae

Raph Hamers is a fellow infectious diseases and clinical immunology at the Academic Medical Center of the University of Amsterdam, and a post-doctoral research fellow at AIGHD. Raph Hamers trained as a medical doctor and internal medicine resident in the Netherlands. In 2003-2004 he was based at the Universidade Federal de Roraima in Brazil, working as a junior lecturer and researcher. In 2006 he joined PharmAccess Foundation in Amsterdam where he established and coordinated the Pan-African Studies to Evaluate HIV Resistance (PASER) network, which aim is to build regional capacity for the population-based assessment and prevention of HIV drug resistance.

In 2007, he co-founded the Affordable Resistance Test for Africa (ART-A) consortium, a public-private partnership that has developed a low-cost testing algorithm for HIV drug resistance. He obtained a post-graduate diploma in Epidemiology from the London School of Hygiene and Tropical Medicine in 2011 (With Distinction). His research at AIGHD, under mentorship of Prof. Tobias Rinke de Wit and Prof. Peter Mugyenyi, led toward the completion of his PhD at the University of Amsterdam in 2013 (Cum Laude). His PhD thesis is entitled “Drug-resistant HIV-1 in sub-Saharan Africa. Clinical and public health studies”. He serves as an Expert Consultant to the WHO Global HIV Drug Resistance Network.

In 2014, he received a prestigious 3 year post-doctoral Veni fellowship granted by the Netherlands Organization for Scientific Research through the Innovational Research Incentives Scheme. His research interests include the molecular epidemiology, diagnostic strategies and clinical management of drug-resistant HIV, HIV-induced chronic immune dysregulation, and models of optimal health care delivery in low and middle-income countries.
