Scholarly Activity


All fellows participate in research regardless of which training pathway they choose. Fellows in the Physician-Scientist Pathway participate in two years of formal research training, supported by the Division’s T32 GI training grant from the National Institutes of Health.

Fellows in the Clinician-Teacher Pathway get weekly academic half-days for scholarly activity and can request research months during their second and third year of training. Scholarly activity is broadly defined and includes research projects, quality improvement/patient safety projects, and review papers/book chapters/editorials. Clinician-Teachers can participate in any or all of these activities as their interests develop, and all are considered equally meritorious for this purpose.

GI Faculty meet with the fellows monthly in work group sessions to help fellows troubleshoot and facilitate research. Fellows also routinely present at the Division’s weekly conference and are encouraged to undertake a quality improvement project. Below is a list of sample projects from fellows resulting in peer-reviewed journal publications.
