Marco Rinaldo Oggioni went to Medical School at the University of Siena (Italy) and later at the University of Verona (Italy) where he obtained his medical degree (1990). During these years he spent a period as guest investigator at the Rockefeller University, New York (USA). Back at the University of Siena he obtained a specialisation degree Microbiology and Virology (1994). His research work started in Siena with Prof. Gianni Pozzi on biotechnological projects aimed at using non-pathogenic streptococci as life vaccine vectors. From 1993 to 2013 he was employed at the University Hospital of Siena and had a series of teaching contracts at the University of Siena, including the course of Molecular Microbiology in the Master´s Programme in Medical Biotechnology taught in English. His two distinct research groups at the hospital and the university focussed respectively on innovative molecular diagnostics and molecular mechanisms of drug resistance and on the other hand on the molecular pathogenesis and genomics of the human pathogen Streptococcus pneumoniae. In 2013 he joined the Department of Genetics of the University of Leicester where he was awarded with a Chair position in Microbial Genetics.
