My research focuses on the transcriptional regulation of blood cell development. We especially are interested in identification of transcription factor in hematopoietic stem cell (HSC) and progenitor cell development. Particular emphasis is on the role of ZBP-89, SCL and other transcription factor in HSC development. We are currently utilizing multidisciplinary approaches to understand how these transcription factors regulate HSC fate determination. These methods include zebrafish, murine embryonic stem cell and mice models as well as biochemical assays.
