Director, Anatomic Pathology
Gastrointestinal Pathology, General Surgical Pathology
My research interests in gastrointestinal pathology include collagenous and lymphocytic colitis, ulcerative colitis, Crohn's disease, infectious diseases of the GI tract, and other non-neoplastic GI disorders. Fatty liver disease, associated with obesity, is also a focus.
