Research Summary

Our research projects focus on sensory afferent neurobiology and nerve-immune interactions in the GI tract. Specifically, we are interested in studying the cellular and molecular mechanisms underlying vagal afferent nerve activation and mast cell activation-induced sensitization of vagal nociceptive afferents in the esophagus.
