I am a Consultant Obstetrician subspecialising in Fetal Medicine and abnormally adherent and invasive placenta (placenta accreta spectrum disorder). I graduated in Clinical Medicine from the University of Oxford and trained within the Oxford Deanery. During my training I completed a Doctorate in Obstetric Ultrasound here in the Nuffield Department of Obstetrics and Gynaecology.

I have a weekly high risk obstetrics ante-natal clinic at the Horton Hospital in Banbury and also lead the FMU Placenta Clinic which provides a tertiary referral service to the Thames Valley region and beyond.

I co-authored both national (RCOG) and international (FIGO) guidelines for the classification, diagnosis and management of abnormally invasive placenta (AIP: now called placenta accreta spectrum, PAS) and am the lead author on the IS-AIP evidence based guideline for intra-partum management of AIP. I am also working with NHS England to develop a national network for the improved management of PAS. I represent the UK to and am elected Vice Chair of the International Society for PAS (IS-PAS) and an elected representative to the European Placenta Group Committee.

Expertscape recently ranked me as one of the top three experts in the world for my work on placenta accreta (
