Research Summary

Our research program is directed at understanding epithelial cell ion transport processes along the intestine. We are especially interested in how these transport processes:

  1. Support stratified communities of beneficial bacteria living within the gut;
  2. Create distinct microenvironments within the mucus coating of the colon;
  3. Give rise to diarrhea in defense against pathogenic intruders;
  4. Become impaired in and contribute to inflammatory bowel disease.
