Expertise & Research Interests

Dr. Rattan is internationally recognized as an outstanding educator and researcher. He is frequently invited as a visiting Professor. Dr. Rattan has received multiple National and International awards in research and teaching.

In 1997, he received a prestigious Janssen Award for his outstanding basic research in Gastroenterology.

In 2006, he was honored by the Council of Indian Organizations as an outstanding professional.

Dr. Rattan's research has been continuously funded by the National Institutes of Health.

He has been an Associate Editor of GASTROENTEROLOGY, on editorial board of, and a reviewer for a number of prestigious journals.

Research Interest: Disorders of the internal anal sphincter (IAS) underlie many clinical abnormalities, such as fecal incontinence and constipation, hemorrhoids and anal fissures. Such disorders are of particular importance in the growing population of the elderly. The focus of Dr. Rattan's research has been on: 1. the nature and role of inhibitory neurotransmitters and mediators; 2. the neural pathways in the rectoanal inhibitory reflex; and 3. the molecular bases underlying myogenic tone in the IAS. Using IAS as the model of tonic smooth muscles, Dr. Rattan's basic studies have provided major advances in the field of molecular biology of the tonic versus phasic smooth muscles. The concepts learnt from his studies have direct implications in the molecular mechanisms underlying pathophysiology, and in the targeted therapeutic development in the gastrointestinal motility disorders, and in a number of other organ systems.
