Having won an open entrance scholarship, Raj Rai qualified from St Thomas’s Hospital Medical School in 1988. He was awarded his MD in 1999 after submission of his thesis on Antiphospholipid antibodies and recurrent miscarriage. After completion of sub-specialty training in Reproductive Medicine (Hammersmith Hospital / St Mary’s Hospitals), he was appointed Clinical Senior Lecturer at Imperial College and NHS Consultant Obstetrician and Gynaecologist at St Mary’s Hospital in 2002.

His main research interests lie in (a) the relationship between antiphospholipid antibodies and other haemostatic abnormalities, recurrent miscarriage and later pregnancy complications; (b) immune disturbance in pregnancy failure and (c) surgical correction of both congenital and acquired uterine defects and pregnancy loss. He is author of the RCOG Scientific Advisory Committee Opinion Paper on Immunological Testing and Interventions for Reproductive Failure and co-author of the RCOG Guidelines on the Investigation and treatment of women with recurrent miscarriage. Most recently he is the PI of the HTA – funded (£1.4 million) multi-centre placebo controlled trial assessing progesterone supplementation in the treatment of women with ‘unexplained’ recurrent miscarriage – the PROMISE study.
