Sir Peter Ratcliffe grew up in north Lancashire and won an open scholarship to study medicine at Gonville and Caius College, Cambridge. He undertook clinical training at St. Bartholomew’s Hospital, London, and after series of posts at the London postgraduate hospitals, moved to Oxford to train in nephrology. In 1990 he obtained a Wellcome Trust Senior Fellowship to work on cellular responses to hypoxia, retrained in molecular biology and founded a new laboratory working on hypoxia biology in cancer and circulatory diseases.  He was appointed Nuffield Professor and Head of the Nuffield Department of Clinical Medicine in 2003, a position he held until 2016. He is currently Director of the Target Discovery Institute, and a Member of the Ludwig Institute for Cancer Research.  He is a Fellow of the Royal Society and the Academy of Medical Sciences and is an honorary member of the American Academy of Arts and Sciences. In the 2014 New Year’s Honours List, he was knighted for services to clinical medicine.

Research Interests

Professor Ratcliffe has led the hypoxia biology laboratory at Oxford for more than 20 years. The laboratory discovered the widespread operation of a system of direct oxygen sensing that is conserved throughout the animal kingdom and operates through a novel form of cell signalling involving post-translational hydroxylation of specific amino acids. Catalysis of these hydroxylations requires molecular oxygen and this generates the oxygen-sensitive signal. The laboratory now works extensively with Professor Chris Schofield in Chemistry to define the extent of biological operation and the therapeutic tractability of drug-based manipulation of the system in human disease.
