Nephrology Fellowship

Nephrology Fellowship

The Pediatric Nephrology Fellowship provides fellows with the knowledge and expertise to be highly effective clinicians and investigators who can improve the lives of children with kidney disease.

Nationwide Children’s and The Ohio State University College of Medicine appreciate your interest in our Pediatric Nephrology Fellowship Program. We believe that you will find we offer many excellent opportunities to help you develop and refine the skills necessary to become a well-trained pediatric nephrologist and accomplished investigator in the areas of clinical and/or basic science.

The Pediatric Nephrology Fellowship Program’s goal is to assure that each fellow finishes our program with the knowledge and expertise to be a highly effective clinician and investigator who can improve the lives of children with kidney disease. Our fellow positions are fully supported by Nationwide Children's Hospital and we offer one to two positions per year. Upon successful completion of the program our fellows will have met the training requirements for Pediatric Nephrology certification by the American Board of Pediatrics.

What You Need to Know

Program Overview

Our program encompasses three years of training, with the goal of preparing trainees for a productive career in Pediatric Nephrology. The first year is focused on clinical training, while the latter two years increase the time allotted to develop a focus in research while continuing valuable clinical training.

Pediatric Research Training

  • Fellows are provided opportunities for clinical, translational and basic science research. They will also learn how to prepare abstracts and manuscripts for publication as well as poster and oral presentations for regional and national meetings.
  • During fellowship training program, submission of at least one first-authored basic science or clinical research manuscript are required to meet ABP requirements for academic pediatric fellowships. However, we encourage our fellows to develop a wide variety of scholarship skills. These can take the form of contributing to a multicenter study, case studies or case series, review articles, text book chapters, and how to participate as a peer reviewer for academic journals. As a result of this emphasis and mentoring, all of our fellows graduate with multiple publications and presentations at national meetings. We encourage our fellows to submit original work for grant proposals (intramural and national sources) in order to gain experience in applying for funding.
  • All fellows work with a mentor to help reach these goals.
  • Each fellow has a Scholarship Oversight Committee responsible for providing direction and oversight of the fellows’ research experiences. These committees include three to five faculty members and meet officially twice a year.
  • Each fellow is required to complete Institutional Review Board training and attend The Research Institute's Fellows Research Training Series.
  • Opportunities to participate in course work at The Ohio State University or complete an MPH, MS in Medical Science, MBA or MHA at The Ohio State University funded by the Department of Pediatrics are available to interested candidates.


Each fellow is evaluated on a monthly basis by the faculty assigned to precept the monthly rotation and semi-annually by the identified research mentor. The fellowship director will meet with the fellow every six months to review the evaluations, procedure lists, continuity patient lists and also discuss the fellow’s academic progress, individualized learning plan, in-training examination score and future plans.

Additional Core Competency evaluations are directed to assessing competence in procedural skills, written communications, verbal communications, professionalism, practice based learning and quality improvement techniques, and understanding relevant health care systems. The fellow will be expected to complete an evaluation of the faculty for each rotation and participate in scheduled Division, Clinical, Research and Fellowship Program reviews.
