Nephrology Fellowship Program

The MedStar Health - Georgetown University Hospital Fellowship Program in Nephrology

Thank you for your interest in the MedStar Georgetown University Hospital Division of Nephrology and Hypertension within the Department of Medicine. This website contains information directed towards those interested in considering a fellowship in our Division. Our goal for the fellowship is to train the next generation of leaders and successful clinicians in nephrology.
For over 50 years, Georgetown has stood at the forefront of nephrology training programs with the aim of producing the very best nephrologists. Trainees undergo a rigorous clinical and investigative program specializing in all major aspects of adult nephrology including:

  • Chronic kidney disease
  • Acute kidney injury
  • Hypertension (Home of the Georgetown University Hypertension Research Center)
  • Acid-base disorders
  • Electrolyte disorders
  • Glomerulonephritis
  • Pregnancy related renal disease (Home of the Georgetown University Center for the Study of Sex Differences in Health and Disease)
  • Onco-nephrology (in close collaboration with the Georgetown Lombardi Comprehensive Cancer Center)
  • Kidney transplantation (MedStar houses the only Renal Transplant Institute in Washington, DC)

Our fellowship training program is approved by the ACGME (Accreditation Council of Graduate Medical Education). We typically accept 3 fellows per year into the training program depending on available ACGME slots and candidate qualifications. Georgetown has a diverse class of fellows who enjoy great camaraderie and a friendly environment in a superb multicultural capital city with outstanding sporting and recreational activities. Georgetown has a prominent research program with a strong focus on both basic science and clinical projects. The hard work and dedication of the clinical and basic science faculty as well as a strong partnership with the Washington DC Veteran Affairs Hospital makes Georgetown one of the pre-eminent nephrology research divisions in the United States.

Why train here

At the Division of Nephrology and Hypertension at MedStar Georgetown University Hospital, our goal is to train outstanding clinical nephrologists and investigators for positions in either academic or private practice. Our faculty are dedicated to our fellows and are always working with our fellows to optimize their learning experience. The second year of fellowship provides an opportunity to tailor the experience to each fellow’s interests through clinic, research and scholarly activities. We host the Mid-Atlantic Nephrology Fellows research forum annually.

Georgetown nephrology fellows receive training as they rotate through the inpatient and outpatient services, and through a series of lectures delivered by faculty and fellows. Fellows should expect to accomplish the following:

  • Become confident in all aspects of nephrology practice and a wide range of problems encountered by patients with kidney disease, renal transplant or hypertension. Fellows receive instruction in taking an appropriate history, performing a complete physical examination and generating an appropriate differential diagnosis.
  • Understand the pathophysiologic basis of kidney disease and hypertension.
  • Develop a full understanding of the laboratory and imaging methods used to evaluate patients with kidney disease.
  • Understand the principles of hemodialysis, peritoneal dialysis, home hemodialysis, plasmapheresis, continuous renal replacement therapy and how to write both acute and chronic dialysis prescriptions.
  • Learn to diagnose and treat a variety of primary and secondary kidney diseases.
  • Understand the principles of immunosuppression and how to evaluate the potential renal transplant donor and recipient.
  • Acquire a thorough understanding of the management of the renal transplant recipient.
  • Learn to critically evaluate a scientific publication

The first year of fellowship focuses heavily on clinical training. MedStar Georgetown University Hospital encompasses three ICUs (medical, surgical, and neurosurgical), several IMC units, a solid organ transplantation ward (where kidney, pancreas, liver, and multi-visceral/small bowel transplants recipients receive their care), an oncology ward, and many other general medical and surgical ward floors. This creates a well balanced environment providing a wide variety of clinical cases for inpatient training. The goal is to provide first class clinical training but also to respect fellows time and to provide a good opportunity for reading. In order to limit the patient load of each individual fellow and allow adequate time for didactics on rounds, the services are divided into three teams, each with its own fellow and attending:

  1. Acute Inpatient Service – this service manages episodes of acute kidney injury, acid base disorders, electrolyte disturbances, hypertensive disorders, onco-nephrology, and pregnancy related disorders in non-dialysis and non-transplant patients
  2. Chronic/Dialysis Inpatient Service – This service focuses on the care of established dialysis patients (both hemodialysis and peritoneal dialysis) and plasmapheresis patients in the inpatient hospital setting
  3. Transplant Service – This service cares for all renal transplant patients and for renal disease in many other solid organ transplant patients including liver transplants, small bowel/multi-visceral transplants, pancreas transplants, and lung transplants.

Each team is composed of one fellow, one attending, and rotating Georgetown or visiting internal medicine residents, and medical students. MedStar Georgetown has five certified transplant nephrologists who run the Transplant service. Chanigan Nilubol, MD, is a full time faculty member in the Division of Nephrology and Hypertension and a trained and experienced transplant nephrologist. There is also a surgical transplant team with its own transplant surgery attending to provide a multi-disciplinary environment for these complex patients. There is a strong focus on clinical teaching while rounding. The aim is to provide an environment that is thought provoking with an open forum for questions and opinions. The inpatient teams provide consultative services since medical patients at Georgetown are admitted by Department of Internal Medicine hospitalists. This permits the fellows to concentrate on the nephrology problems of the patient. Fellows receive training in many clinical services and procedures including: inpatient hemodialysis, inpatient peritoneal dialysis, continuous renal replacement therapy modalities in the ICU, slow continuous ultrafiltration, urine sediment microscopy, temporary hemodialysis catheter insertion (with real time ultrasound guidance), kidney biopsies (native and transplant), and plasmapheresis.

Each fellow participates in a rotating continuity outpatient clinic at Georgetown University Hospital throughout their training. The clinic is typically one half day a week. The fellow rotates every 6 months to interact with different faculty and specialty clinics. A few clinics focus on some selected nephrology topics including chronic kidney disease, resistant and secondary hypertension, onco-nephrology, and kidney transplantation. Other clinics see general nephrology with a mix of different pathologies.

The second year of fellowship focuses on outpatient dialysis, outpatient clinics, and on research. Fellows typically will rotate through the DC Department of Veterans Affairs Hospital for one of their outpatient clinics. Outpatient dialysis training is undertaken at the Georgetown University DaVita Dialysis units at Union Plaza and the “Home Only” unit on Wisconsin Avenue and at the Department of Veteran Affairs Hospital. Georgetown has the first “Home only” dialysis unit in Washington DC specializing in peritoneal dialysis, home hemodialysis and nocturnal home hemodialysis training. Fellows receive training in these rapidly expanding modalities.


Didactics are complemented by:

  • Dahlgren Library Access
    • Provides access to a multitude of Nephrology references such as Brenner and Rector’s The Kidney / KDIGO Guidelines / Pathology Atlas / ECT
  • Access to PubMed
  • Access to UpToDate
  • Full reimbursement to attend the NKF conference (first years)
  • Full reimbursement to attend the ASN conference (second years)
  • A personal copy of the Handbook in Nephrology and Hypertension by Christopher Wilcox, M.D., Ph.D. and the Primer on Kidney Diseases by Arthur Greenberg, M.D.
  • Transplant Nephrology Lecture Series

    The clinical transplant nephrologists lead a didactic series focused on all aspects of renal transplantation.

    The transplant lecture series is designed to give additional background and to provide a literature review on selected topics. The structure of the series is designed to transition from more passive learning (primarily directed lectures on selected topics) early in the year to more active participation (in the form of case conferences) and ultimately to get the nephrology fellow to lead the teaching by the end of the year (through case conferences and their own presentations). Lectures are attended by the transplant nephrology fellow, the surgical transplant fellows and the general nephrology fellows allowing each discipline to add their own experience and viewpoint to the discussion.

    In addition to providing information on a variety of topics, the series is also designed to highlight the strengths and weaknesses in the transplant literature and provide examples of common features and problems found in the design of transplant studies. It is hoped that the literature reviews enable better critical thinking by the fellow in reviewing research and in designing their own research protocols.

    Transplant Lecture topics include:

    • Introduction and Overview of Transplantation
    • Transplant Immunology
    • Tissue Typing
    • Pathology- Banff Classification
    • Clinical Aspects of Rejection
    • Kidney Allocation Policy
    • Recipient Evaluation
    • Donor Evaluation
    • Calcineurin Inhibitors
    • mTORs and celecept
    • Antimetabolites
    • Steroids and Steroid Sparing Agents

Elective Rotations

Thank you for your interest in rotating at MedStar Georgetown University Hospital! All residents and fellows wishing to rotate at MGUH must apply directly to the department in which their training will take place. Please contact the coordinator for the sub-specialty with which you wish to rotate. Applications are processed on a first-come, first serve basis.

Eligibility & Process: All visiting residents and fellows must be enrolled in an ACGME-accredited training program in addition to satisfactorily and punctually completing the steps outlined below:

  • At least 120 days prior to the start of the desired rotation dates the visiting resident/fellow will obtain approval from the Program Director for the rotation by emailing the program coordinator the following:
    • CV
    • Requested rotation dates
    • PGY level
    • Name of your program director
    • Name and email of your program coordinator
  • If approved based on CV and availability on service, we will work with your program coordinator to create and sign a Program Letter of Agreement (PLA).
  • Once we have a fully executed PLA our GME office will reach out directly to the rotator with a checklist of required documentation via our residency management system, New Innovations.

Note: GME must have the fully executed PLA no later than 4 weeks before the start of the rotation.

  • If you do not have a full DC license all rotators will also need to apply for an MTR (medical training registrant) with the Board of Medicine in order to be allowed to rotate in the state of DC. You can check the status of your application. A “Pending” status usually means they have received your application. Typically, the license does not become “active” until a day or two before the rotation. If your license is not active by Day 1 of your rotation, please get in touch with the BoM directly to find out where the problem lies.
  • Once the rotator has completed the New Innovations checklist, the GME office will notify the program that you are good to rotate. A week or so prior to your start you should receive a welcome email from the Georgetown program coordinator with check-in instructions (including, parking, ID badge, computer training and team contacts). Please feel free to reach out if you have not heard from your GUH coordinator by this point.
