Current Research and Scholarly Interests
My research interests are in the development of effective and cost-effective clinical approaches to treating gastrointestinal diseases, with an emphasis in Crohn's disease and ulcerative colitis. Using large databases, patient-reported outcomes, and decision science (e.g., Markov modeling), my overarching research goal is to optimize the use of various diagnostic and therapeutic strategies to improve patients' health, healthcare delivery, and pharmaco-economics of chronic gastrointestinal diseases - thereby informing patients, clinicians, and policy makers. Aside from inflammatory bowel disease, I am interested in applying available data and translating innovative ideas (e.g., technology, social media, and bioinformatics) to other complex chronic diseases, especially those with child health significance, through collaborative and inter-disciplinary efforts. Recently, we have adapted our investigations into the study of celiac disease, liver transplantation, functional abdominal pain, childhood obesity, acute and chronic diarrhea (e.g., Clostridium difficile infections), and microbiota. Whenever possible, our research attempts to compare the health and economic impact of clinical decisions from a health policy standpoint.
