Hematopoiesis, the biology of blood cell generation is an intricate and complex process that is vital for the health and survival of all mammals including human beings. Accordingly, any malfunctions in this process often lead to life threatening diseases such as anemias, leukemias and lymphomas. An investigation of the molecular mechanisms involved in producing normal blood cells is therefore essential for understanding the onset and progression of many hematopoietic diseases.
Our research focuses on the interplay between transcription factors and their co-regulators (genetic factors) and the chromatin alterations they catalyze (epigenetic processes) in orchestrating gene expression patterns that in turn program the fate and function of hematopoietic stem and progenitor cells. To address these issues, we utilize a combination of genetic, biochemical and molecular biological approaches including tissue culture manipulation of human and mouse cells in vitro and genetic manipulation of mice in vivo.
