Professional background

Anton Emmanuel obtained his medical degree from London University. He is a professor in neuro-gastroenterology at University College London and consultant gastroenterologist at UCLH and the National Hospital for Neurology and Neurosurgery (Queen Square). Prior to this he was senior lecturer at Imperial College and honorary consultant gastroenterologist at St Mark's Hospital.

His clinical work encompasses being director of the GI Physiology Unit at University College Hospital, as well as providing a neurogastroenterology service. The Physiology Unit provides state-of-the-art testing of oesophageal and anorectal function, as well as a wide range of therapies for patients with neurogastro and functional disorders – biofeedback, neuromodulation, transanal irrigation, hypnotherapy, psychological services, dietetic input. 

His research includes gut neurophysiology and the study of the aetiology and management of functional gastrointestinal disorders of the upper and lower gut. He is editor in chief of Clinical Medicine and medical director of publishing at the Royal College of Physicians.
