Biography
Florent Ginhoux graduated in Biochemistry from the University Pierre et Marie CURIE, Paris VI and obtained a Masters degree in Advanced Studies in Immunology from the Pasteur Institute, Paris. He then started his PhD in the Immunology Team of GENETHON, Evry and obtained his PhD in 2004 from the University Pierre et Marie CURIE, Paris VI.  As a postdoctoral fellow, Florent Ginhoux joined the Laboratory of Miriam Merad in the Mount Sinai School of Medicine (MSSM), New York where he studied the ontogeny and the homeostasis of cutaneous dendritic cell populations, with a strong focus on Langerhans cells and Microglia. In 2008, he became an Assistant Professor in the Department of Gene and Cell Medicine, MSSM and member of the Immunology Institute of MSSM. He joined the Singapore Immunology Network (SIgN), A*STAR in May 2009 as a Principal Investigator. He joined the EMBO Young Investigator (YIP) program in 2013 and is a Web of Science Highly Cited Researcher since 2016. He is also an Adjunct Visiting Associate Professor in the Shanghai Immunology Institute, Jiao Tong University, in Shanghai, China since 2015. Both laboratories are focusing on the ontogeny and differentiation of macrophages and dendritic cells (DCs).

Research interests
Dendritic Cell and Macrophage Ontogeny: Dendritic cells (DCs), monocytes and macrophages play crucial and distinct roles in tissue homeostasis and immunity, but also contribute to a broad spectrum of pathologies and are thus attractive therapeutic targets. Potential intervention strategies aiming at manipulation of these cells will require in-depth insights of their origins and the mechanisms that govern their homeostasis. The focus of the laboratory is to understand the ontogeny of DCs, monocytes and macrophages, their differentiation pathways and how their unique ontogeny dictates their immune functions. 

Our approach encompasses the integration of high dimensional platforms such as RNAseq, single cell transcriptome analysis using microfluidic RNA sequencing and deep immunophenotypic assessment using state of the art 18 parameters flow cytometry or Cytometry by Time-Of-Flight mass spectrometry (CyTOF). Such high density molecular profiling at the single level and at unprecedented dimensionality and complexity will provide new insights in the biology of DC, monocyte and macrophage cell populations. Defining macrophage and DC populations on the criteria of their origin may aid our understanding of their discrete roles in tissue immunity and homeostasis, as ontogeny of DC and macrophage subsets likely underlie their functional specializations.
