The Surgical Intervention Trials Unit (SITU) is team of surgical investigators which will act as a training and development hub for surgical trialists within the UK. Our directors are Professor Freddie Hamdy, Nuffield Professor of Surgery and Professor David Beard, Professor of Musculoskeletal Sciences

About us

Working as part of the Oxford Clinical Trials Research Unit (OCTRU – Directed by Professor Sallie Lamb and Professor Doug Altman) we aim to be a centre of excellence for the design and management of surgical trials, welcoming surgical trials which aim to answer important problems in the UK and worldwide.
