EBV-associated T/NK lymphoproliferative disorders are an important group of diseases because they are prevalent in Asia and clinical outcome is generally dismal as there are no reliable prognostic markers and effective therapy is lacking. The pathobiology of EBV-associated T/NK lymphomas is poorly understood and the role of EBV in the oncogenesis is yet to be established. Hence, it is important to conduct in-depth study into the pathogenesis and molecular mechanisms of these tumours.

In the last few years, my research focus has been on EBV-associated T/NK-cell lymphoproliferative disorders, and in particular, extranodal NK/T cell lymphoma (NKTCL). Using a combinational analytical approach via gene and miRNA expression profiling on paraffin embedded tissue samples, we have uncovered the molecular signatures and important oncogenic pathways in NKTCL, and identified novel biomarkers and potential therapeutic targets. The long term goal is to delineate and validate key biomarkers and oncogenic pathways in NKTCL and identifying molecular subsets of prognostic and clinical importance.
