Professor David Williams

Professor David Williams
  • Consultant Obstetric Physician

Clinical Care

Professor Williams is a consultant obstetric physician who provides clinical care for pregnant women with acute or chronic medical disorders, a specialty known as obstetric medicine.

At the Institute for Women’s Health, University College London Hospital (UCLH) he leads multi-disciplinary teams in the clinical care of pregnant women with kidney disease, inflammatory bowel disease, rheumatological diseases, neurological diseases, heart and endocrine disorders. Professor Williams has expert knowledge of safe prescribing in pregnancy that maximises benefit for the mother and minimises adverse effects to the developing fetus.

Professor Williams has particular expertise in the management of pregnancy-induced ‘gestational’ syndromes. These include pregnancy-induced hypertension and pre-eclampsia, gestational diabetes, hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, blood clotting disorders and pregnancy-induced skin diseases.


At University College London (UCL), he leads research into the causes and management of:

  1. Pre-eclampsia
  2. Acute Fatty Liver of Pregnancy
  3. Recurrent pregnancy loss, in particular due to Chronic Histiocytic Intervillositis (CHI)
  4. The paternal genetic contribution to fetal growth and development.

He developed the concept that gestational syndromes unmask a woman’s vulnerability to disease in later life.

Other Roles

Professor Williams is chairman of the ‘Wellbeing of Women’, Research Advisory Committee. He is a member of the UK Maternal, Newborn and Infant Clinical Outcome Review Independent Advisory Group that monitor annual reports on maternal and perinatal morbidity and mortality. In 2019, he was chairman of the UK NICE guideline on the intrapartum management of medical disorders in pregnancy. Professor Williams lectures and publishes widely on obstetric medicine. With the Obstetric Medicine Company, he leads an annual course for clinicians on medical disorders in pregnancy and at UCL, he leads an MSc on Pregnancy and Childbirth.
