The Renal Fellow Network (RFN) was established on April 23rd, 2008 by the late Nathan Hellman. RFN was created to provide a forum to discuss interesting nephrology cases, scientific papers, and other topics germane to nephrologists, particularly fellows. The goal is to present cutting edge nephrology-related research and challenging clinical topics in an easily digestible format.

In September 2018, RFN announced a partnership with the American Society of Nephrology (ASN). The RFN-ASN partnership is a great opportunity to solidify and ensure RFN remains a valuable asset to future nephrology fellows from around the world. Read our perspective in CJASN discussing this partnership here.

Interest in the site has continued to grow. Approximately 45% of our readers are fellows, 20% attendings, 20% are residents or medical students and 5% are involved in full time research according to the poll conducted on our website.

RFN is an educational resource maintained on a voluntary basis. As such, RFN does not endorse nor accept advertisement from industry. If commenters post material that is deemed advertisement reviewers will delete the comment from the site without warning. Furthermore, the site adheres to strict patient confidentiality principles outlined by HIPAA.

Editorial Process- All posts are peer reviewed by a member of the RFN Editorial Team. First review is from a member of the RFN faculty advisor group and a second review is from both the RFN editor and RFN Faculty Lead. All submissions are screened using Ithenticate

Her interest in medical education on developing and dissemination of home dialysis curriculum.

Kelly Hyndman, PhD is an assistant professor in the Division of Nephrology at the University of Alabama at Birmingham. Dr. Hyndman is a basic scientist whose research focuses on the physiological role of histone deacetylase (HDAC) enzymes in the regulation of fluid-electrolyte balance in mammalian models. However, deranged HDAC activity correlates with a number of cardiovascular and renal diseases, and in the setting of ischemia/reperfusion injury, Dr. Hyndman’s lab is investigating the putative contribution of HDACs in the progression of chronic kidney disease. She also serves on the ASN Media and Communications Committee.

Tanecia Mitchell, PhD is an assistant professor at the University of Alabama at Birmingham in the Department of Urology, School of Medicine.
