Pediatric Nephrology Fellowship Program

Children's Healthcare of Atlanta, in collaboration with Emory University School of Medicine, offers three-year fellowships in pediatric nephrology to qualified, promising physicians.

Our goal

Our goal is to train academically oriented pediatric nephrologists who will be involved in a lifetime of excellence in patient care, teaching and research. Upon successful completion of our training program, fellows will:

  • Be experts in the pathophysiology of pediatric kidney disorders
  • Be skilled in the clinical diagnosis and management of these disorders
  • Have developed a foundation for the scholarly advancement of our field

About Our Program

First-year fellows spend nearly the entire year dedicated to clinical activities. Second- and third-year fellows primarily spend their time in research (with 16 months of clinical emphasis and 20 months of research emphasis).

Accreditation and funding

Our fellowship program is accredited by the Accreditation Council for Graduate Medical Education (ACGME). There is funding for one or two new fellows each year (four positions total) to be fully supported through the entire three-year program.


First-year fellows spend nearly the entire year dedicated to clinical activities. Second- and third-year fellows primarily spend their time in research (16 months clinical emphasis and 20 months research emphasis).

First year

Clinical training (10 months)

  • Manage patients with a wide variety of kidney disorders
  • Assignments to the inpatient wards
  • Learn skills, such as renal biopsy and ordering dialysis
  • Provide consultation to other services, including the Pediatric, Neonatal and Cardiac Intensive Care Units
  • Manage all acute dialysis modalities and a high volume of continuous renal replacement, predominately in the form of CVVH
  • Manage all perioperative phases of pediatric renal transplant recipients
  • Gain advanced knowledge of fluid and electrolyte management

One month entails full-time assignment to the Children’s at Egleston affiliated hemodialysis unit where fellows have in-depth training in principles, literature and application of dialysis as well as the opportunity for hands-on familiarity with hemodialysis and peritoneal dialysis equipment and techniques.

Introduction to research (2 months)

  • Two months of the first year are dedicated to research orientation with an initial opportunity for project selection
  • Fellows also participate in department-wide courses in Research Fundamentals, Teaching to Teach, Medical Ethics and Quality Improvement methodologies

Second year


  • Consecutive research months in which fellows finalize the selection of research projects and mentors and initiate selected projects

Clinical assignments (2 months)
One month will be a mixture of important experiences including a course with Dr. Charles O’Neill in the Emory Department of Medicine Division of Nephrology, learning ultrasound for the nephrologist. This course is virtually unique in the country and one that numerous practicing nephrologists have taken with excellent reviews.

Additional experiences include teaching sessions with the Emory Histocompatibility (HLA) laboratory, observation of pediatric renal transplant surgeries, interactions with our pediatric renal pathologists, and clinical sessions with our pediatric urology colleagues.

Third year

  • Completion of research project, abstract(s) and manuscript(s)
  • Completion of Quality Improvement project
  • Advanced clinical responsibilities in the inpatient wards (2 months)

Continuity clinics

During the entire three-year training period, fellows attend assigned continuity outpatient clinics a half day per week under the supervision of the program director.

On-call schedule

On-call schedule

  • Fellows take weekend call on average every fourth weekend throughout the three-year training period and weeknight call twice weekly during inpatient weeks only. Night call is always taken from home. An attending pediatric nephrologist is always on back-up call with the fellow.
  • Fellows on-call round with the attending physician on the inpatient service during weekends and holidays.
  • Fellows will average three two-day weekends off every four weeks.

Fellows are entitled to three weeks of vacation per year that may be taken at any time during research or outpatient rotation months with approval from the program director.

Each fellow is given the opportunity to attend Camp Independence—one of the oldest and largest camps in the country for children with kidney failure. Camp Independence takes place one week each summer at Camp Twin Lakes, a venue developed specifically to provide life-changing programs to Georgia’s children with serious illnesses, disabilities and other challenges.

Research training

In addition to clinical training, fellows pursue mentored research. The area(s) of concentration will be selected based on the interest of the fellow who is responsible for designing, implementing and completing a hypothesis-driven project with the guidance of a Scholarship Oversight Committee of advisors and mentors.

Fellows are encouraged (albeit not required) to apply for and secure external funding for their research endeavors and submit the results of their research for dissemination in an appropriate scholarly venue. Research opportunities are diverse and plentiful and may include collaboration with investigators from other divisions, departments or schools within Emory University.

Fellows interested in a career focused on clinical research are encouraged to apply for Emory's Master of Science in Clinical Research (MSCR) program.
