Research Summary
The majority of my time is spent in clinical activities, teaching and running the fellowship program. Thus, my research interests are focused mainly on quality improvement projects with fellows and clinical projects with residents interested in applying for GI fellowship. Past projects have included examining patient preferences for colon cancer screening modality in collaboration with Liana Fraenkel MD, Department of Medicine, Rheumatology, examining the location of angioectasias within the small bowel using capsule endoscopy, and looking at outcomes for different modes of endoscopic treatment of angioectasias in patients with significant GI bleeding. Additionally, I have collaborated in the past with Dr. Pichamol Jirapinyo Pichamol Jirapinyo and Christopher Thompson MD, Brigham and Women's Hospital, Harvard, on a project looking at the use of a part-task endoscopy simulator in endoscopy training. The simulator was developed by Drs Jirapinyo and Thompson and we participated in a randomized control trial of its use in first year fellows among other studies. Past quality improvement projects have included identifying a mechanism to effectively notify patients of their lab and imaging results within 2 weeks at our VA GI clinic and testing a mechanism to calculate fellow adenoma detection rates. Currently I am doing a retrospective evaluation of the impact of high resolution white light endoscopy as well as newer iterations of endoscopes on detection rates of sessile serrated adenomas.
