Research Summary

Our IBD Program group does clinical research with inflammatory bowel disease (IBD) patients including evaluating and treating depression in patients with inflammatory bowel disease and setting up databases to correlate genotype with phenotypic expression. We participate in several international multi-center trials for different medications and databases.

Our HHT group does clinical research in patients with hereditary hemorrhagic telangiectasia (HHT) who also have gastrointestinal (GI) bleeding.

Extensive Research Description

Inflammatory bowel disease - our IBD Program group does clinical research with inflammatory bowel disease (IBD) patients including evaluating and treating depression in patients with inflammatory bowel disease and setting up databases to correlate genotype with phenotypic expression. We participate in several international multi-center trials for different medications and databases.

HHT - Along with other members of our HHT Center, our group does clinical research in patients with hereditary hemorrhagic telangiectasia (HHT) who also have gastrointestinal (GI) bleeding.

GI Match - Collaborating with other colleagues, we have done research on the GI fellowship match.

1. Treating depression in patients with inflammatory bowel disease

2. Multi-center trials for new drugs in inflammatory bowel disease

3. Correlation of genotype with phenotypic expression in patients with inflammatory bowel disease

4. Global health training attitudes in trainees
