Current Position: I am the Scientific Director of the Oxford Centre for Fetal Monitoring Technologies based in the Nuffield Department of Obstetrics and Gynaecology(NDOG). We work in tight collaboration with the Institute of Biomedical Engineering.

My main interests lay in the development of evidence-based computerised methods to monitor childbirth and improve clinical outcomes. This is novel and only possible because of a unique database available in Oxford (more details for our data). The goals are: (a) early detection of babies at risk of intrauterine asphyxia – a preventable cause of brain damage, and (b) reduction of the number of unnecessary interventions.I work closely with the Clinical Director of the Centre - Prof. Chris Redman (Emeritus Professor in Obstetrics & Gynaecology).


The priority of the Oxford Centre for Fetal Monitoring Technologies is to pioneer a real-time prototype for intrapartum CTG analysis similar to its antepartum analogue - System 8000, developed in NDOG earlier by Prof Dawes and Prof Redman in the 1980-90s and produced by our industrial partner Huntleigh Healthcare. Several slides presenting the problem at hand can be seen here.
