Academic Interests

Dr. Gounari is interested in signal transduction pathways that are involved in the development of hematopoietic stem cells into the T-cell lineage and deregulations that lead to leukemia. A major focus of research is the pre-T-Cell Receptor, that triggers the expansion and differentiation of immature thymocytes. Her work has demonstrated a cross talk of preTCR signaling with the Wnt/beta-catenin and Notch cascades. Both Wnt/beta-catenin and Notch have been directly linked with human cancer. Dr. Gounari is currently studying the physiological versus pathological interactions of these pathways in developing versus transformed thymocytes.
