Rodrigo Abreu

Center for Vaccines and Immunology
Postdoctoral Research Associate, Ross Lab


Rodrigo B. Abreu received his doctorate in infectious diseases from the University of Georgia in 2018 for his work on the impact of iron export in macrophages during tuberculosis infection. During his graduate years, Dr. Abreu showed that TLR signaling in macrophages can lead to intracellular iron sequestration in macrophages through redundant yet independent mechanism, and the relevance of such mechanisms for intracellular replication of siderophilic bacteria such Mycobacterium tuberculosis. To complement his training in innate immunology, he has recently joined Dr. Ross Lab at Center for Vaccines and Immunology, to work on the adaptive immune response to influenza in humans. As a Post-doctoral fellow, he will focus on the crosstalk of the adaptive and innate immune system during influenza infection or vaccination, with a particular interest in systems serology.
