These IFFGD research awards were given to active investigators who have a record of research interest in basic mechanisms or clinical aspects of functional gastrointestinal and motility disorders. The awards are intended to encourage the participation of clinicians and scientists in multidisciplinary efforts aimed at advancing the understanding of gastrointestinal disorders in adults and in children.

Basic Science is the fundamental approach to understanding how systems work. Basic research takes place in the laboratory and often involves the study of molecules and cells.

Clinical Science is the approach aimed at understanding the diagnosis and treatment of diseases and disorders through studies involving people, usually carried out in clinical settings.


The awards were presented by Nancy Norton, President, IFFGD; Frank Hamilton, MD, Chief, Digestive Diseases Programs Branch, National Institute of Diabetes and Digestive and Kidney Diseases of the NIH; and Douglas Drossman, MD, Chair, IFFGD Research Awards Selection Committee.
