I started as a microbiologist with a graduate university thesis on prophages in H. Pylori. Subsequently I became passionate about molecular and cellular biology, starting to work on a research project on artificial chromosomes in humans. Subsequently I became interested in the immunology of tumors and autoimmune diseases starting from my Ph.D thesis on monoclonal antibodies produced in bacteria and plants for therapeutic use against Erb-b2, up until now when I am mainly interested in autoimmune diseases.
