Dr Sáez-Cirión received his PhD in Science in 2001 from the University of the Basque Country, Leioa, Spain. He joined the Institut Pasteur in Paris as a Postdoc in 2003 after a first postdoctoral period at the FDA-CBER in Bethesda. He leads now a research team in the HIV Inflammation and Persistence Unit. His research is currently focused in understanding (i) the mechanisms underlying control of HIV infection in natural HIV controllers and post-treatment controllers in remission of HIV infection after interruption of antiretroviral treatment; (ii) the factors associated with the establishment of HIV reservoirs and devising new approaches to tackle them.
