Professional background

Farooq Rahman is a consultant gastroenterologist at University College Hospital and honorary associate professor at University College London.

He studied medicine at The Royal Free Hospital School of Medicine in London and completed his specialist training on the North East London rotation. He obtained his PhD from UCL studying the immunopathogenesis of inflammatory bowel disease.

He is a luminal gastroenterologist with subspecialty interests in inflammatory bowel disease, clinical nutrition & intestinal failure and radiation enteropathy. He also maintains a busy clinical practice and has extensive experience in general gastroenterology and colonoscopy. He maintains a strong commitment to undergraduate/postgraduate teaching and training and training and remains actively involved in clinical and translational research.
