Nephrology Fellowship

The Division of Nephrology at Children’s National offers a comprehensive three-year ACGME accredited fellowship program.

As a nationally-recognized program for more than 30 years, we provide fellows with a unique experience that combines excellence in clinical training and world-class research opportunities. Our mission is to produce well-trained pediatric nephrologists who excel in every aspect of care for children and adolescents with kidney disorders.

Our fellowship provides comprehensive training  in all aspects of clinical nephrology and the provision of acute and chronic renal replacement therapy. This includes acute and chronic peritoneal dialysis (PD), acute and chronic hemodialysis (HD), continuous renal replacement therapy (CRRT), intensive care nephrology and renal transplantation.

As a fellow, you also will participate in scholarly research activities available within the Division of Nephrology, the Children’s Research Institute, the National Institutes of Health (NIH) and the George Washington University Schools of Medicine & Health Sciences and Public Health.

Didactic lectures on end-stage renal disease and transplantation, small group discussions and opportunities to teach faculty/medical students are a core part of the program’s curriculum.



Our program encompasses three years of training, divided among four primary clinical experiences over a total of 17 months. 

The first year is primarily focused on clinical training, while the latter two years increase the time focus on research and scholarly activities.

First rotation includes 10 months of direct inpatient and consultative patient care

  • This encompasses the care of patients on the pediatric nephrology inpatient service, the provision of acute renal replacement therapies, care for new kidney transplant recipients and general nephrology consultations for hospitalized children and adolescents.
Second rotation, focused on end-stage renal disease, encompasses a total of five months
  • Fellows work closely and collaboratively in the outpatient hemodialysis unit and peritoneal dialysis programs to provide outpatient renal replacement therapy.
  • Fellows actively participate in all aspects of the kidney transplant program, including outpatient kidney transplant clinic, patient review conferences and the pre-transplantation clinic.

Third rotation focuses on general outpatient nephrology experience

  • Extensive time in the outpatient nephrology and transplant clinics at Children’s National.
Fourth rotation
  • Two weeks devoted to a multispecialty rotation, in which fellows spend time in outpatient urology and rheumatology clinics, radiological services including renal ultrasonography and nuclear imaging.
  • Two-week intensive renal pathology experience at the George Washington University School of Medicine & Health Sciences.


Each fellow is evaluated on a monthly basis by faculty leading clinical rotations as well as semi-annually by their identified research mentor. Competence is assessed in procedural and technical skills, practice-based learning, written and verbal communications, professionalism and knowledge of relevant health care systems. Every six months, each fellow will meet with the Program Director to discuss in-training exam scores, academic progress and individualized learning plans.
The fellow will also be expected to complete an evaluation of each teaching faculty member in the division semi-annually.

Comprehensive Research Training

The fellowship offers dynamic opportunities for clinical, translational and basic research under the guidance of NIH-funded researchers. Each fellow will be paired with a research mentor and a scholarship oversight committee, responsible for providing direction and oversight of the fellows’ research projects.

In addition to learning how to prepare abstracts and manuscripts for publication, submission of at least one first-authored basic science or clinical research manuscript is required from each fellow. (Multiple abstracts to scientific meetings are encouraged). Each fellow is required to complete the Fellows Core curriculum offered through
Children’s National. 

Fellows are also provided an opportunity to further their research education through either master’s level degree granting programs or individual coursework. The master's level degree granting programs include either a Masters of Science in Health Sciences (MSHS) in Clinical and Translational Research granted through the George Washington University (GWU) School of Medicine & Health Sciences or a Master’s of Public Health granted through the GWU School of Public Health.

Fellows will learn how to prepare abstracts and manuscripts for publication for regional and national meetings.
