The Experimental Medicine Division is a collection of research groups within the Nuffield Department of Medicine who are based at a number of sites including the John Radcliffe Hospital, the Peter Medawar Building for Pathogen Research, the Churchill Hospital, including Old Road Campus, the Nuffield Orthopaedic Hospital and the Weatherall Institute of Molecular Medicine.

Our researchers seek to understand the pathophysiology of disease and apply this knowledge to develop enhanced diagnostics and treatments for human disease. Our research research spans fundamental basic science to translational and experimental medicine approaches including clinical trials. Our areas of focus include immunology, behavioural science, infectious diseases, gastroenterology, palliative care and respiratory medicine. 

The Experimental Medicine Division employs 200 active scientific research staff working in a range of basic science and clinical disciplines, with many contributing to the teaching of medical students within Oxford University's Clinical School. Many staff hold honorary contracts with the NHS, in addition to NHS employees holding University of Oxford honorary contracts. Research includes immunology, infectious diseases, gastroenterology, respiratory medicine, palliative care, and genetics of genomics.

The administration team oversees the Division's research grants, finances, HR, IT and Laboratory management and is based at the John Radcliffe Hospital on Level 5 with many of the Units having smaller teams of administration who are linked to the main administrative office. There are also a large number of postgraduate research students.

In partnership with the University, the OUHT was selected in 2006 to host one of the NIHR's five comprehensive Biomedical Research Centres (BRC) with a budget in excess of £20 million per annum. 

Experimental Medicine Theme leaders within the BRC include:

• Professor Paul Klenerman - Gastroenterology and Mucosal Immunity
• Professor Derrick Crook and Professor Tim Peto - Antimicrobial Resistance & Modernising Microbiology
• Professor Ian Pavord - Respiratory Medicine
