Gastroenterology Fellowship

The Gastroenterology and Hepatology Fellowship at Indiana University School of Medicine trains outstanding gastroenterologists in a three-year ACGME-accredited program that combines excellent clinical and academic training. The program curriculum is tailored to each individual fellow’s career goals. Core program values include diversity, equity, and inclusion. Learn more about the school's DEI values via the GME diversity website.

Education and mentoring are critical to the Division of Gastroenterology and Hepatology, which hosts one of the most robust general gastrointestinal and advanced therapeutic endoscopy fellowships in the United States. Former trainees of this program are now leaders at academic medical centers throughout the United States and successful practicing gastroenterologists in Indiana and beyond.


Five gastroenterology fellowship positions are available each year at IU School of Medicine. Apply through the Electronic Residency Application Service (ERAS).

Welcome from GI Fellowship Leadership

Program Director's Message

Thank you for your interest in the GI Fellowship program at Indiana University School of Medicine! IU School of Medicine is the largest medical school in the nation, and our division is one of the largest and most comprehensive GI Divisions in the country and the only tertiary care center for gastroenterology and hepatology for the state of Indiana. Our program supports, guides and prepares fellows to reach the maximum of their potential, to realize their personal goals and to succeed in their future careers whether at academic institutions or community practices. With the prominence and commitment of our large group of faculty, with diverse strengths and interests, we offer our fellows a broad spectrum of GI training in a tailored three-year program. With multiple training sites on the downtown Indianapolis campus, our fellows experience the unique and different strengths of each site, and a comprehensive educational experience in clinical training and research.

In alignment with the IU School of Medicine core values, our program offers a positive and inclusive experience, in an environment that embodies excellence, respect, collegiality, integrity, diversity and cooperation. The well-being of our fellows is equally important to us to the quality of the education we provide them.

I, along with the entire GI division faculty and staff, wish you the best as you move forward with your career plans and invite you to further explore our program. We look forward to hearing from you soon.

I will support you starting from your interviews, throughout your onboarding, three years of training, and culminating with your graduation.

Associate Program Director's Message

Hello prospective fellows! My role as Associate Program Director (APD) fits with my career mission of helping colleagues at all levels develop the most fulfilling careers possible. In this role, I work on curriculum and professional development. While all our fellows are well-trained in general gastroenterology, I hope you leave here with special skills needed to advance academic medicine and the health of our Hoosier community in the coming decades. I will work to help you build the career that is the best fit for you. One of our biggest strengths is our faculty – we have excellent mentors for a huge range of clinical topics. Ask me about our GME pathways – Leadership, Health Equity, Global Health, and Clinician Educator. I’m also happy to discuss other training opportunities available through IU, such as business, public health, research, informatics, ethics, and Omics. I look forward to meeting you!

Associate Program Director's Message

I am an Assistant Professor of Medicine in the Division of Gastroenterology and have the privilege of holding the Associate Program Director (APD) position for the fellowship program.

I am also a graduate of the Gastroenterology Fellowship program and chose to stay as faculty in the thriving research environment of the division. My role as an APD encompasses research guidance, oversight, and advocacy for fellows. Feedback from the fellows' about "feeling heard" and being "able to make changes to the established systems" to positively impact their clinical learning environment, makes my role as APD very rewarding.

We wish you an enriching, invigorating, and meaningful time here. We are sure you will find the extraordinary training you came to seek with us. We are pleased and humbled that you chose to spend your precious years of training with us. We hope you become the physician you always dreamt of being and care for those you have always yearned to serve.

And always remember, you are never too busy to be kind, make friends and enjoy the ride.

Here at IU, I lead a team that is committed to promote the use of social media primarily for information sharing with friends of the division. We post links to articles and videos that showcase the clinical and research accomplishments of the faculty and fellows. Our content on ongoing events within the division is reflective of our culture and values. We believe that social media offers a platform for collaborative learning of gastroenterology and hepatology related interests. We encourage our faculty and fellows to follow other educators, key opinion leaders, journals, and professional societies to keep up with the latest trends, research, and best practices in education. Social media has helped us connect with our educators around the world, our alum and potential fellowship candidates. We are very mindful of privacy concerns and take steps to protect personal information. We hope that our efforts may set up virtual exchanges and collaborations with other like-minded educators and learners from different countries or regions.
