Department Name/Job Location
This position is in the Department of Pathology/Immunology, Division of Immunobiology. This position is for the Medical School Campus.
A postdoctoral position is immediately available to study molecular mechanisms that regulate hematopoietic and vascular development and regeneration. My lab has expertise on hematopoietic, vascular and stem cell biology as well as stem cell applications and has made significant contributions to the understanding of how hematopoietic and vascular systems are established during embryogenesis. We utilize an in vitro differentiation model of embryonic stem (ES) cells and early mouse embryos to address self-renewal, lineage commitment, and differentiation of the hematopoietic and vascular systems. We are currently focusing on several transcription factors that control commitment from mesoderm to FLK1 expressing mesoderm and from the FLK1 expressing mesoderm to hematopoietic and endothelial cells. Our current projects include 1) transcriptional control of hematopoietic and vascular cell lineage development, 2) directed differentiation and application of hematopoietic and vascular progenitors from stem cells, 3) hematopoietic stem cell biology, 4) hematopoietic and vascular repair and regeneration mechanisms, 5) tumor angiogenesis, and 6) tumor endothelial cell targeted gene delivery.
