Dr. Paolo Fiorina obtained his medical degree from the University of Milan and continued his training at the combined Internal Medicine/PhD program in immunology at Parma University. After studying transplantation immunology for six years at the San Raffaele Scientific Institute in Milan, one of the leading programs in human islet cell transplantation, Dr. Fiorina joined Boston Children's Hospital as a research fellow in 2004. In 2009 he became an Assistant Professor of Nephrology at Boston Children’s/Harvard Medical School.

Dr. Fiorina’s research focuses on diabetes. In particular, he is interested in three major areas: (1) the treatment of autoimmune diabetes; (2) the replacement of beta cells through islet transplantation; (3) the treatment of diabetic nephropathy. Dr. Fiorina has made significant and innovative contributions in understanding the mechanism underlying the beneficial effects of life expectancy obtained after islet transplantation, even when patients only have partial islet function.
