Research focuses on the cellular physiology of intestinal electrolyte transport.
Current projects are examining the effect of hormones and growth factors on small intestinal epithelial differentiation, particularly development of ion transport pathways and the role of subepithelial fibroblasts in the growth and differentiation of epithelial cells. The studies require the use of physiological, biochemical and morphological methods of assessing the degree of differentiation and function of the epithelial cells.
