Gregory S. Sayuk, M.D., M.P.H.

Assistant Professor of Medicine and Psychiatry

Associate Director, Fellowship Training Program

Dr. Gregory Sayuk joined the Division of Gastroenterology in 2006.  He completed his medical school training at the University of Texas in Houston (1996-2000) and then came to Washington University for his Internal Medicine Residency training (2000-2003) and Gastroenterology fellowship (2003-2006). Dr. Sayuk trained under the mentorship of Dr. Ray Clouse, and has a clinical interest in irritable bowel syndrome (IBS) and related functional GI disorders.

IBS represents a condition whose pathogenesis remains incompletely understood.  Dr. Sayuk collaborates with Washington University colleagues in Neuroradiology and Psychiatry to perform neuroimaging research using functional magnetic resonance imaging (fMRI) technology to identify central symptom amplification mechanisms and defective pain inhibitory pathways that may be relevant to IBS pathophysiology.
