Endocrinology Fellowship

Endocrinology Fellowship

Nationwide Children's Hospital offers a three-year pediatric Endocrinology Fellowship.

Dear Applicant,

Thank you for your interest in the Pediatric Endocrinology Fellowship training program at Nationwide Children’s Hospital! We offer a fellowship program fully sponsored by the Endocrinology Division at Nationwide Children’s. Our program provides an excellent opportunity for achieving clinical, research and academic training. As the only major pediatric center in central and southeastern Ohio, you will get exposure to both routine and rare cases in endocrinology. Being a part of T1D exchange collaborative also provides opportunities for leading quality improvement initiatives with potential for multi-site collaboration. Fellows have opportunities to pursue clinical and translational research with mentorship from endocrine faculty as well as faculty from varied disciplines and areas of research at the Abigail Wexner Research Institute.

The fellowship program accepts two fellows per year. Our three-year training program can be structured to meet the specific interests and goals of a trainee, enabling them to succeed in their career as an academic and clinical pediatric endocrinologist. We welcome you to explore our website to learn more about Columbus, Nationwide Children’s, our fellowship program, faculty, current fellows and alumni.

What You Need to Know


The fellowship curriculum provides a balance of clinical, research and academic experience. Nationwide Children’s Hospital is well positioned to provide a valuable clinical exposure for fellowship training. As the primary referral center for Central and Southeastern Ohio, it provides a robust exposure to evaluating and managing common and rare endocrine disorders. To provide experience in longitudinal care of children with endocrine disorders, throughout the fellowship, fellows see patients in a continuity clinic one half-day per week. Fellows learn to provide care in a collaborative environment working with a dedicated team of providers including pediatric nurse practitioners, physician’s assistants, endocrine nurses, certified diabetes educators, dietitians, and social workers. Fellows also get to experience real world diabetes management at Camp Hamwi, the Central Ohio Diabetes Camp, and providing opportunity to work with children from ages 7 to 18 years. Opportunities for mentorship from faculty both within and outside of division, and from various centers in the Abigail Wexner Research Institute provides a strong clinical and translational research experience. Fellows have opportunities to write grants, present findings at national and international conferences and publish their work in high impact journals. Dedicated time for academics throughout the fellowship program facilitates uninterrupted learning through a variety of tools.

The focus of the first year of the fellowship program is clinical experience, with an introduction to research opportunities. Structured as two-week rotations, fellows spend about 45% time in inpatient, 25% time in outpatient and about 20% time in research rotations. During inpatient rotations, fellows are either on consultation service or the inpatient service with a supervisory attending. Fellows are expected to take primary ownership of these patients. The outpatient rotation consists of fellows attend faculty diabetes and general endocrinology clinics and receive case-based teaching and education. Of the research rotation, 4 weeks will be in the first half, 2 weeks in middle and 4 weeks in second half of the first year. The first is used to explore various research opportunities and identify mentors (with guidance from the program director), with subsequent blocks used to develop the research proposal for the second and third year. There is also a one week clinical laboratory rotation to learn how endocrine assays are performed and the factors that may affect result interpretation.

The second and third years of the program are primarily research-focused so that the fellow can successfully lead and complete a primary project of their choice. Each fellow has a Scholarship Oversight Committee to supervise their research activity and is composed of the fellowship program director and research mentors from within and outside the division. Fellows maintain their half day of continuity clinic per week. Additionally, they participate in several subspecialty clinics one half day per week. These include Metabolic Bone Health clinic, Cystic Fibrosis Related Diabetes, Neuro-oncology survivorship clinic, Bone marrow Transplant clinic, THRIVE clinic (for patients with differences of sex development, gender development), Prader-Willi syndrome clinic, 22q11 clinic, PCOS clinic, Turner syndrome clinic and type 2 DM clinic. Second year fellows do 4 weeks of inpatient rotation. Third year fellows do 8 weeks of inpatient rotation, half of which will be at the end of the third year in preparation for future attending responsibilities. Second and third year fellows will also work with our well-recognized Pediatric Endocrinology Quality Improvement Program and opportunities exist in a variety of fields including clinical care in diabetes mellitus, endocrine disorders and workflow improvements. There are also opportunities to do electives in adolescent gynecology, adult endocrinology, healthy weight and genetics.

Dedicated conferences for fellows’ education continue throughout the three years of the program, and includes Endocrine physiology lecture series, Disease pathophysiology and clinical management lecture series, Journal clubs (on hot off the press and older but landmark articles), Case discussions, Joint radiology-endocrinology conferences, board review sessions and Diabetes conferences. Several physiology lectures are given by fellows allowing them to enhance oral communication and presentation skills. Guest lectures are given by renowned faculty from outside the division and visiting professors.

Research Experience

Fellows are expected to have a hypothesis driven research project as their main scholarship activity during fellowship. This can be a clinical, translational or basic science research project. Research opportunities are available in the Clinical Research Center of The Ohio State University and the Clinical Study Center of The Abigail Wexner Research Institute at Nationwide Children's Hospital.

Additional unique resources available to you as a fellow at Nationwide Children’s Hospital will be:

  • Access to an Intramural Grant program for funding your research study.
  • Opportunity to pursue a number of master’s degree programs through The Ohio State University, including but not limited to Master of Public Health (MPH), Master of Medical Science, Master of Clinical Research and Master in Biomedical Education. The Department of Pediatrics is pleased to offer competitive funding opportunities for fellows obtaining a master’s degree.
  • Fellow’s College educational series: a lecture series provided by Nationwide Children’s specifically for fellows. The college consists of three pillars: core curriculum, professional development and scholarship.

Testimonials From Our Alumni

“The attendings were all amazing and interested in teaching, and I felt very comfortable approaching every one of them for assistance with patients, or any other question from career advice to mentorship with projects.”

“The entire endo team had so much camaraderie, and I learned so much from the nurses, CDEs, dieticians, and social workers as well. I also have an interest in Medical Education, and I was also able to attain funding through Nationwide Children's Hospital for Masters level classes in Med Ed (which I am now using frequently in my career).”

“I lived in Columbus for 15 years and it is an amazing city to live in. Traffic is minimal and the cost of living is great, it is a growing city with so much to do. I was there before being married and while raising a young family, and we really loved what the city has to offer.”

“I would definitely choose Nationwide Children's for fellowship again and would recommend the program to anyone.”
