About the Program

The general objective of the Nephrology fellowship at the Ohio State University is to provide the trainee with a comprehensive experience in clinical nephrology and, for those following the research track, an indepth research experience that will prepare them for a career in academic nephrology. The specific objectives of the program are as follows:

  • Provide a detailed experience in clinical nephrology and its procedures appropriate to both the hospital and out-patient setting.
  • Integrate clinical training with the clinical and basic sciences through regular didactic sessions.
  • Encourage the pursuit of research activities and the development of problem solving skills.
The members of the Nephrology faculty are dedicated to providing the Nephrology trainee with a broad base of clinical and research skills leading to board certification in Nephrology and a productive career as a clinical or research Nephrologist.

Nephrology fellowship paths

In addition to providing excellent training in all aspects of nephrology, the Division of Nephrology is well-known for unique strengths in several areas including glomerulonephritis, kidney and pancreas transplantation, interventional nephrology, renal pathology and combined adult-pediatric nephrology.


We are internationally known for our expertise in both basic and clinical research in glomerulonephritis (GN). We have a weekly multidisciplinary glomerulonephritis clinic attended by our fellows. With this strength, in partnership with the Division of Rheumatology, we have had three successful years with a dedicated GN fellowship. This is a non-ACGME accredited position is available after the completion of the traditional fellowship. Currently, we have five clinical and one research faculty leading this unique training program.

Critical Care Nephrology

We have several faculty members with a special interest in critical care nephrology, providing training in acid-base electrolyte disorders, CRRT and citrate based anticoagulation. Daily, we have over 20 patients on CRRT, providing the opportunity to obtain expertise in this modality.


The Nephrology Fellowship at The Ohio State University Wexner Medical Center consists of two years of clinical nephrology training, with equal emphasis on inpatient and outpatient medicine. Interventional nephrology training is integrated during the fellowship for those candidates interested in pursuing practice opportunities in this field. 

In addition, a third year of training is available in glomerular diseases or transplantation. If funding is available, a third year of research fellowship training may be taken.
