Dr Sibtain Anwar



Sibtain (Sibs) Anwar read Neuroscience alongside Medicine at the University of Cambridge receiving First Class Honours for his research thesis on the effects of melatonin on excitatory projections within the brain. He completed clinical training at Imperial College London, while also pursuing his research interests as an Honorary Fellow of the Academic Cardiology Unit at The National Heart and Lung Institute. He investigated the effects of autonomic nervous system activation on the QTc interval, under the supervision of Professor Desmond Sheridan.

After completing specialist medical training in Australia and at the University College London Hospitals, Sibs received advanced training in Cardiothoracic Anaesthesia, Critical Care and Pain Medicine. This was followed by fellowships at Harefield Hospital, The Royal Marsden, The Royal Brompton, St.Thomas’ and the Guy’s Thoracic Unit.

He also spent four years as a Research Fellow at the William Harvey Research Institute where he studied the Systems Neuroscience of Persistent Postsurgical Pain. His work culminated in the award of a PhD from the University of London and the Young Investigator Award from the American Pain Society. This was followed by an invitation to speak at the ‘Rising Stars of Anaesthesia’ Jubilee Symposium of the National Institute of Academic Anaesthesia.

Sibs is now a Senior Lecturer and Consultant in the Department of Perioperative Medicine at the Barts Heart Centre - Europe’s largest cardiovascular institution. He also sits on the Pain Medicine Council at the Royal Society of Medicine.
