Welcome to the Endocrinology, Diabetes, and Metabolism Fellowship at the University of Iowa. If you are interested in a fellowship program that would prepare you for a career in clinical and or academic medicine, we are the program for you. Our program is designed to provide fellows a broad foundation in general Endocrinology while allowing the flexibility to pursue diverse interests to achieve individual career goals.

The Fraternal Order of Eagles Diabetes Research Center affords additional opportunities for our trainees to pursue cutting-edge research. 

Our program is located in a city that has been described as one of the best cities for college graduates, one of the best places to live and one of the coolest towns in America.

Thank you for your interest in the Endocrinology, Diabetes, and Metabolism Fellowship at University of Iowa. Fellows who complete our program are well-positioned to become leaders in whatever career path they choose, in clinical practice or academic medicine. In addition to comprehensive clinical training, our program offers numerous opportunities to obtain training in basic or translational research and in medical education. Our faculty and educational leadership are prepared to work with you on an individual basis to construct a model that aligns with your long-term career goals, while also ensuring that you excel in the foundational skills every endocrinologist must know.

Another aspect that makes our fellowship program unique is the combination of a premier research center with substantial research funding to support a great variety of research activities. Even those fellows considering a mostly clinical track should be aware of the number of research opportunities that exist in our Fraternal Order of Eagles Diabetes Research Center and the Specialized Program of Research Excellence in Neuroendocrine Tumors. We are on the cutting-edge of research discoveries but also possess the resources to implement other initiatives in the clinical setting.

If you have any questions or would like to discuss what opportunities exist for you at the University of Iowa, please free to get in touch with us.
