Lai (Lisa) Wei’s research interests are functional roles of enterochromaffin (EC) cells in GI physiology and pathophysiology of gastroparesis and disorders of gut-brain interaction, and the crosstalk between EC cells and gut microbiota and its derived molecules under different pathological conditions. Also work on surgery-induced adhesions (“scar tissue”) murine models and AAV-mediated gene therapy, aiming to target specific GI cells to alleviate or prevent abdominal adhesion formation.
