The bulk of teaching occurs in a hands on setting devoted to the GI pathology fellowship and resident training. His research interests are primarily in the area of unusual enteropathies. One major subtype of unusual enteropathies includes endocrinopathies of the GI tract. Other rare pathological conditions related to intestinal failure, intestinal transplant, HIV enteropathy, NSAID injury, also contribute to the spectrum of unusual enteropathies studied by Dr. Cortina.
