Current Projects

Effect of Dietary Folate Supplemenation and Depletion on Human Colonic Mucosa

Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM)

This is a VA Multisite Study. The purpose of this study is to compare two types of colon cancer screening tests and determine which is more effective in preventing death from colon and rectal cancer. These tests have not been compared in a large study and it is not clear which test is more effective Role: Site Principal Investigator/Local Site Investigator


Drug Induced Liver Injury - causality determination



Research Summary

Major goal of our research is to identify molecular pathways that modulate the risk of colon cancer.
