About

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. RFN averages 70,000 page views and site visits per month, and 50,000 unique site visits per month. Interest in the site, as reflected in number of unique page views, 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 a non-profit 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.

Pravir V. Baxi, MD is an assistant professor of Medicine in the Division of Nephrology at Rush University Medical Center in Chicago. He received his medical degree in 2011 from Wayne State University School of Medicine in Detroit. He completed his Internal Medicine Residency and subsequent Nephrology Fellowship at Rush. His clinical interest is in the management and treatment of glomerulonephritis. He enjoys teaching and has become involved in promoting medical education via several social media platforms. He currently serves as a co-director of the GlomCon Interactive Fellows’ Curriculum which aims to enhance the education of trainees and connect training programs to foster a culture of collaborative learning. @Proximal_Baxi

Anna Burgner, MD, MEHP is an assistant professor in nephrology at Vanderbilt University Medical Center, and the associate nephrology fellowship program director. She completed her internal medicine residency and nephrology fellowship at Vanderbilt. After completing her nephrology fellowship, she obtained a Master of Education in the Health Professions from Johns Hopkins University. Her time is split between clinical practice, teaching medical students, residents, and fellows, and clinical research. Her clinical interests are broad and include treatment of kidney diseases during pregnancy, prevention of kidney stones, and transitioning pediatric nephrology patients to adult nephrology clinics. Her research interests include slowing the progression of kidney disease, particularly diabetic nephropathy, hypertensive nephrosclerosis, and polycystic kidney diseases. She also serves on the ASN Media and Communications Committee. @anna_burgner

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. @DrKeeksPhD

Jennie Lin, MD is an assistant professor of medicine in the Nephrology and Hypertension Division at Northwestern University Feinberg School of Medicine. She is a NIH K08 funded physician-scientist whose research is focused on functional -omics studies of cardiometabolic and kidney diseases. Her group focuses on (1) the role of RNA biology in mechanisms of lipid metabolism, atherosclerosis, and renal fibrosis and (2) functional interrogation of the molecular mechanisms by which novel genes identified through human genetics studies impact disease phenotypes. Outside of work, she loves spending time playing with her beagle Penelope and her beagle-basset Calvin, enjoying introvert time on her Kindle, and bragging about her Texan roots, and eating her way through Chicago. @jenniejlin

Andrew Malone, MB BCh is an assistant professor of medicine in the Division of Nephrology at Washington University in St. Louis.
