2005 IFFGD Research Awards Recipients

These IFFGD research awards (2005) 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.

Peer-Review Selection Committee

  • Ronnie Fass, MD
  • Samuel Nurko, MD
  • Reza Shaker, MD
  • Yvette Taché, PhD
  • Jackie Wood, PhD

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.


We congratulate the 2005 IFFGD Research Award recipients for their outstanding achievements.

The 2005 award for Senior Investigator in Clinical Science went to Fernando Azpiroz, MD, PhD at Hospital General Vall d’Hebron, Barcelona, Spain. 

Dr. Azpiroz has a large clinical practice, and his research program looks at the causes of gastrointestinal symptoms including gut motility and sensitivity, and more recently, intestinal gas.

Read Dr. Azpiroz’ Research Summary, “Understanding Intestinal Gas.”

The 2005 award for Senior Investigator in Basic Science went for Yvette Taché, PhD at West LA-VA Medical Center, UCLA, Los Angeles, CA. 

Dr. Taché’s early publications put the “brain-gut axis” on the map. Her recent research looks at the brain pathways involved in stress-related alterations of gut function and pain.

Read Dr. Taché’s Research Summary, “Stress and Irritable Bowel Syndrome: Unraveling the Code.”

The 2005 award for Junior Investigator in Clinical Science went to Shaheen Hamdy, MRCP, PhD at Hope Hospital, Salford, United Kingdom. 

Dr. Hamdy’s interest is in the brain-gut axis, in particular how the brain controls swallowing and anal continence. His work has involved the treatment of swallowing problems after a stroke, as well as understanding fecal incontinence of unknown origin.

Read Dr. Hamdy’s Research Summary, “Adult Neurogenic Dysphagia: Disorders and Conditions that Disrupt Swallowing.”

The 2005 award for Junior Investigator in Basic Science went to Michael Pezzone, MD, PhD at the University of Pittsburgh, Pittsburgh, PA. 

Dr. Pezzone is currently the principle investigator of an NIH study looking at the cross-communication of nerves in the pelvic organs and how this leads to the overlap of irritable bowel syndrome, interstitial cystitis, and other chronic pelvic pain disorders.

Read Dr. Pezzone’s Research Summary, “Chronic Pelvic Pain and the Overlap of Chronic Pelvic Pain Disorders.”

The 2005 award for Pediatric Investigator in Basic Science went to Bridget R Southwell, PhD at Murdoch Childrens Research Institute, Royal Children’s Hospital, Melbourne, Australia. 

Dr. Southwell researches the causes of disturbed colonic motility in children. She has also been coordinating a method to help children overcome constipation and soiling.

Read Dr. Southwell’s Research Summary, “Treatment-Resistant Constipation in Children.”

The 2005 award for Pediatric Investigator in Clinical Science went to Rachel Rosen, MD, MPH at Children’s Hospital Boston, Boston, MA.

Dr. Rosen’s current research looks at reflux symptoms in children. In her studies, she has found that non-acid reflux is common in children at her practice, and has symptoms such as heartburn, chest pain, and cough.

Read Dr. Rosen’s Research Summary, “Symptoms Arising from Non-Acid Reflux in Children.”
