Dr. Yadlapati, director of the esophageal diseases & motility program, is an actively funded investigator with a clinical-translational research program focused on identifying mechanisms of injury and nociception in reflux disorders, developing and testing novel diagnostic and therapeutic strategies for GERD, and implementing practice guidelines for esophageal diseases. Dr. Yadlapati is the principal investigator of several clinical trials studying the efficacy for novel treatments for laryngopharyngeal reflux, GERD, and eosinophilic esophagitis. Dr. Yadlapati's overarching research objective is to define phenotype guided care paradigms for esophageal conditions. Dr. Mittal's novel research program focuses on the sensory and motor function of esophagus using the state of art techniques, some of which were developed in his own laboratory. He worked extensively on the role of crural diaphragm as an external lower esophageal sphincter in health and disease, studying its control mechanisms. His recent studies have focused on the role of longitudinal muscles of the esophagus in the physiology and pathophysiology of esophageal motor function. His esophageal research has been funded by NIH continuously since 1988 and VA MERIT grants for the last 12 years. For the last 15 years, he has also focused on the pelvic floor and external anal sphincter in the context of fecal continence and incontinence.
