Research Interests

I am interested in translational clinicopathologic research related to the field of gastrointestinal, pancreaticobiliary, and liver pathology. I have specific interest and experience in the study of idiopathic inflammatory bowel disease (Crohn’s and Ulcerative colitis) and low grade appendiceal mucinous neoplasms, though I welcome outreach for collaborative projects pertaining to all areas of gastrointestinal medicine.
