Dr. Kiela has been involved in basic research on various aspects of the gut development, physiology, and pathophysiology for over eighteen years. His particular interest is in the therapeutic and pathophysiological aspects of Inflammatory Bowel Diseases.  His laboratory is involved with pre-clinical studies on the effectiveness and mechanism of action of curcumin (a natural non-specific inhibitor of NF-kappa-B) in mouse models of CD and UC (chemically induced colitis and spontaneous colitis in IL-10 or TCR-alpha knockout mice); the role of NHE3, the major intestinal Na+/H+ exchanger, in the maintenance of epithelial integrity of the gut, and in modulation of the immune response in Inflammatory Bowel Diseases. 

Dr. Kiela is also interested in the effects of acute and chronic colitis and inflammatory mediators on key players of systemic inorganic phosphate homeostasis, and its contribution to osteopenia and osteoporosis frequently associated with IBD. 

Dr. Kiela's membership in the University of Arizona Cancer Center has opened up opportunities to contribute his expertise in collaborations with other members.
