Major Research Areas
Researchers in the College of Graduate Studies focus their efforts where it truly matters—on the diseases and illnesses that affect many people. Much of our research activity is grouped into four areas of concentration: cancer; infectious diseases; disorders of the nervous system; and diabetes, metabolic disorders and cardiovascular diseases.

My laboratory focuses on understanding the molecular and epigenetic mechanisms involved in the regulation of normal hematopoiesis and hematologic malignancies. The ultimate goal of our research is to identify new therapeutic targets and develop novel therapeutic strategies for treatment of leukemia. JAK2, a member of the Janus family of non-receptor protein tyrosine kinases (JAK), is activated in response to a variety of cytokines. A somatic point mutation (V617F) in the JAK2 tyrosine kinase has been found in a majority of patients with myeloproliferative neoplasms (MPNs) including 95% cases of polycythemia vera (PV) and 50-60% cases of essential thrombocythemia (ET) and primary myelofibrosis (PMF). One of the major areas of our research is to define the role of JAK2 and JAK2V617F in hematopoiesis and in the pathogenesis of MPNs. We are utilizing state-of-the-art techniques and genetically engineered mouse models to uncover the mechanisms involved in leukemogenesis.
Current research projects in my laboratory are focused in the following areas:
- Elucidation of the role of JAK2 and JAK2V617F mutation in hematopoiesis and myeloproliferative neoplasms (MPNs).
- Investigation of the role of SHP2 in MPNs, and targeting of SHP2 in MPNs using SHP2-specific inhibitors.
- Investigation of the role of protein tyrosine phosphatase PTPN1 in myeloid neoplasms.
- Investigation of the role of histone methyltransferase EZH2 in the pathogenesis of MF.
- Testing the efficacy of potential new targeted therapies for MPNs using novel animal models.
