My primary research interest involves the molecular pathways that play a role in the pathogenesis of B cell malignancies and their recurrences. These include transcriptional networks that control normal B cell development and maturation, as well as factors that mediate therapy resistance and drive clonal evolution towards relapsed disease. Furthermore, the identification of second primary malignancies may lead to discovery of novel genetic factors that predispose to lymphoid malignancies. Future research will also include studies on the interaction between malignant B cells with their immune microenvironment, which could play an important role in regulating differential immunotherapy responses.
