Dutta Lab



Dr. Florentin received his master’s degree in Human Pathology and Infectious Diseases in 2009 from the Faculty of Medicine Aix-Marseille University, France. He was awarded with the French Ministry of Research and Technology fellowship in 2009 to study the impact of Hepatitis C Virus (HCV) on a subset of cells of the innate immunity, the plasmacytoid dendritic cells (pDCs) in Dr. Ivan HIrsch lab at CRCM-INSERM (France).  In 2013, he obtained his PhD in Human Pathology and Immunology from Aix-Marseille University, France. In 2013, he joined Michael Gale Jr. lab in Seattle, WA, USA, to study the relevance of dendritic cells in the context of West Nile Virus (WNV) and Dengue Virus infections (DenV). In 2015, he joined Dr. William Burlingham’s lab at the University of Wisconsin-Madison, WI, USA to investigate the role of maternal microchimerism derived exosomes in antigen acquisition in the context of transplantation. He then joined Dr. Partha Dutta’s lab in the Vascular Medicine Institute at the University of Pittsburgh, PA, USA, to work on change in hematopoietic stem and progenitor cells and function of inflammatory cells in pulmonary hypertension.
