Pier Giuseppe Pelicci is Director of Research and Chairman of the Department of Experimental Oncology of the European Institute of Oncology, professor at the University of Milan, Scientific Director of Alleanza Contro il Cancro. With a medical degree, a specialty in Internal Medicine and a PhD in Molecular Biology, he contributed to seminal discoveries in the elucidation of mechanisms of tumorigenesis (e.g. identification/functional characterization of PML-RAR and mutated NPM in myeloid leukemia) and the definition of the molecular bases of targeted treatments (retinoic acid, HDAC- LSD1 inhibitors). His current research focuses on the characterization of normal and cancer stem cells in leukemia and breast cancer, molecular mechanisms underlying metastatic dissemination, and mechanisms of DNA damage accumulation in normal and cancer cells.
