Professor and Director of Protein Sciences at the Jackson Laboratory in Bar Harbor Maine, USA.  He is a fellow of the American Physiological Society and the American Heart Association.  His laboratory uses multi-omics systems biology approaches to study blood pressure regulation, cardiovascular genomics and epigenomics, as well as membrane and cellular proteins and their role in cell signaling and cell-cell interaction. His work has helped to characterize the renin-angiotensin system at the cellular, molecular, and whole animal levels and has helped to define the role of the renin-angiotensin-aldosterone system in angiogenesis. Professor Greene also among the first to recognize the importance of bone marrow derived mononuclear and endothelial progenitor cells in angiogenesis and blood pressure regulation and has published several key papers describing the importance of gene-environment interaction in the competency of these cells.
