Professional Interests

My team’s current research goals are to define the critical mechanisms regulating the equilibrium of stem cells. Current and future projects are aimed as follows: 1) to target cellular metabolism for therapy as well as 2) to study the role of microRNA-epigenetics crosstalk in the pathogenesis of myelodysplastic syndrome (MDS).

Metabolic requirements in cell fate decision of hematopoietic stem cells.

Various molecular metabolism mechanisms have recently come into focus as novel regulatory elements of stem cell maintenance. The broad objective of this line research is to illuminate through both genetic and pharmacological approaches the role of one such potential regulatory element, fatty acid metabolism, in the cell fate decisions of hematopoietic stem cells. This line of research has the potential for high impact in the clinic, as we believe a targeted approach to metabolic reprogramming will eventually enhance and extend the health and well-being of patients through the fine tuning of stem cell function.

Targeting leukemia-initiating cells for therapy for MDS and other hematological malignancies.

MDSs are a heterogeneous group of clonal bone marrow malignancies characterized by ineffective hematopoiesis, the presence of dysplastic cells in the bone marrow, and peripheral blood cytopenias. Our lab has devised a plan to identify key mechanisms of MDS pathogenesis for the development of targeted therapies to combat the disease more effectively. Targeting of leukemia-initiating cells (or leukemia stem cells) may be a viable strategy to eradicate residual disease and prevent leukemia relapse. Our expertise in stem cell biology and hematology would benefit, and even potentially cure, the victims of many different forms of hematologic pathology as well as MDS.
