Professional background

Raf Napolitano was appointed as a consultant in obstetrics and fetal medicine in 2017. He is the lead clinician for the ultrasound screening unit and one of the developer of the training programme in obstetric ultrasound and fetal medicine.

He provides a range of diagnostic and therapeutic services on the Fetal Medicine Unit and the Preterm Birth Clinic along with looking after women in labour. Raf obtained his certificate of completion of training in obstetrics and gynaecology at the University of Naples, Federico II, Italy, during which he conducted a fellowship in fetal medicine at St George’s Hospital, London.

Following this, he worked as a post doctoral clinical research fellow at the University of Oxford and undertook the subspecialty training in maternal and fetal medicine at the John Radcliffe Hospital, Oxford.

He was awarded the subspecialty accreditation by the Royal College of Obstetricians and Gynaecologists in 2016 when he then jointed the team of consultants at UCLH. In 2017 he was awarded a PhD in neuroscience at the University of Naples, Federico II, producing a thesis on the development and growth of fetal brain structures using ultrasound as part of the INTERGROWTH-21ST Project.

In 2018 he started a "Late fetal growth restriction clinic" at UCLH every Monday, where all women with babies having growth problems or at risk of compromise are referred.
