David M Shapiro

Assistant Professor of Medicine (Gastroenterology and Hepatology)

I perform primary and secondary endoscopic (non-surgical) therapies for obesity, including placement of the Orbera gastric balloon, the Aspire Assist device and endoscopic sleeve gastroplasty. I also perform gastro-jejunal outlet reduction for weight regain after bariatric surgery. I have also been trained to use the EsophyX device (TIF procedure) as a minimally invasive (non-surgical) treatment for GERD. I am also interested in endoscopic treatment of post-surgical complications and endoscopic suturing.

Marie-Pier Tetreault

Assistant Professor of Medicine (Gastroenterology and Hepatology)

In the Tetreault Lab, our goal is to better understand the crosstalk between epithelial cells and their surrounding microenvironment (immune cells, fibroblasts, endothelial cells). A particular area of expertise of our laboratory is in defining the role of epithelial inflammatory mediators in esophageal tissue homeostasis and esophageal disease pathogenesis. Our diseases of interest include esophageal cancer, eosinophilic esophagitis, scleroderma esophageal disease and achalasia. Our research program focuses on two key inflammatory pathways: the IKKß/NF¿B and STAT3 pathways. We employ novel th...
