Paul Riley is Chair of Development and Reproduction in the Department of Physiology, Anatomy and Genetics at the University of Oxford. He was previously Professor of Molecular Cardiology at the UCL-Institute of Child Health, London, where he was a principal investigator within the Molecular Medicine Unit at UCL-ICH.. Prior to this, he obtained his PhD at UCL (1992-1995) and completed post-doctoral fellowships at the Samuel Lunenfeld Research Institute, Toronto, Canada and the Weatherall Institute of Molecular Medicine, Oxford (1996-1999). In 2008, Professor Riley was awarded the Outstanding Achievement Award of the European Society of Cardiology (ESC) Council on Basic Sciences. The award recognises a landmark discovery in the field of basic cardiovascular science when his team found that Thymosin b4 could mobilise dormant cells from adult epicardium to form new blood vessels in the heart, a major step towards finding a DIY mechanism to repair injury following a heart attack.
