My research interests lie at the intersection of gastroenterology, epidemiology, and real-world data science. I use large administrative and clinical databases to investigate questions in GI motility, infectious disease, and oncology. A significant focus of my work is colorectal cancer epidemiology, including risk factors, treatment-related complications, and the role of the gut microbiome in modulating cancer outcomes. I am also interested in drug-induced GI complications, particularly how commonly used medications affect gut physiology and susceptibility to infection. Additionally, I have a growing interest in esophageal motility disorders and the evolving diagnostic landscape in that field. Across all projects, I employ observational study designs with rigorous causal inference methods, including propensity score matching and sensitivity analyses, to generate clinically meaningful evidence that can inform patient care.
