Professional background

Anton Emmanuel obtained his medical degree from London University. He is a Senior Lecturer in Neuro-Gastroenterology at University College London and Consultant Gastroenterologist at University College Hospital 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 general gastroenterology service. His research includes basic gut neurophysiology and the study of the aetiology and management of functional gastrointestinal disorders of the upper and lower gut. He currently supervises 7 post-graduate research fellows undertaking higher degrees. Laboratory work is undertaken jointly with colleagues in UCL. He is the Chairman of the NeuroGastroenterology section of the British Society of Gastroenterology. He is the Editor of the journal Frontline Gastroenterology.

Patients are assessed within a multi-disciplinary environment, with structural and physiological investigations undertaken as a one-stop visit alongside a focussed clinical assessment. The Unit is always happy to discuss cases by phone in order to streamline referral for the patient.
