Professional background

I am a consultant neonatologist with a special interest in brain injury in babies. I was lecturer in paediatrics, University of Cambridge 1985-1987, and held a consultant appointment in Cambridge until 1995. Whilst in Cambridge I was also director of medical studies at Girton College.

I held an appointment as consultant in neonatal medicine at King’s College Hospital in London from 1995-2004. I held a similar post at University College London Hospitals where I was clinical lead in neonatology. I retired from clinical work in December 2018 but continue to teach and conduct research.

I have contributed chapters to the major British textbook of paediatrics and many other books, and co-authored  “Manual of Neonatal Intensive Care 4th Edition” with Dr NRC Roberton. I am the editor of  “Rennie & Roberton’s Textbook of Neonatology 5th Edition” (in preparation), and the Editor of the 4th edition. I was the sole author of “Neonatal Cranial Ultrasound”, and co-author of the updated version entitled “Neonatal cerebral investigation” (highly commended in the BMA Book Prize 2009 and by Doody’s Book Reviews). I was elected a fellow ad eundem of the Royal College of obstetricians and Gynaecologists in 2008.

I am involved in research into neonatal brain injury, and have published many papers on this topic. Our group currently holds a Wellcome technology transfer grant, for work on automated seizure detection, and I was a co-investigator in a European study (FP-7) of antiepileptic drug treatment of neonatal seizures. I was on the board of the Archives of Disease in Childhood for ten years and served on the national executive committee of the British Association of Perinatal Medicine for a similar length of time. I previously served on the board of the Mac Keith Press. I was the chair of the RCPCH specialist advisory committee, responsible for setting standards regarding training in neonatal medicine in the UK, from 2002 to 2005, having been on the committee since 1997. I have advised CESDI, and RCOG-led advisory groups on “Safer Childbirth” and “Standards for Maternity Care”. 

I was chair of the NICE guideline development group on neonatal jaundice 2007-10. I advised the NHS Atain programme. I was the chair of the NICE guideline group on neonatal care, I advise on the NHS Resolution early notification scheme.
