UW Pediatrics

Nephrology Fellowship


Mission Statement

The mission of the Pediatric Nephrology Training Program is to produce physicians and investigators of exceptional caliber, who will assume leadership roles in the field of academic Pediatric Nephrology.

Program Aims

Produce physician leaders, advancing the field of pediatric nephrology through investigation, education and/or administration.

Train excellent clinicians who are capable of working in multidisciplinary teams that care for children with kidney disease.

Develop young investigators who are competent in the process of scientific inquiry, from study design to data analysis and knowledge dissemination.

Program Overview

Established in 1989, the Pediatric Nephrology Fellowship program benefits from a strong multidisciplinary clinical program that partners a wealth of expertise from specialized nurses (dialysis, transplant and general nephrology), social workers, dietitians and physicians. As the only freestanding children's hospital within a five-state region, we serve children from a large and geographically diverse area, providing our fellows with a breadth of exposure to clinical nephrology.

Our comprehensive fellowship program takes a unique approach to training aspiring pediatric nephrologists across a diverse spectrum of career pathways ranging from a primary clinical career, to those with a strong interest in teaching, as well as conducting research. At the core of our program lies a personalized learning experience, where each fellow collaborates closely with our faculty to forge a unique fellowship journey, building off a strong clinical foundation.

Our division is characterized by a vibrant research environment, with its members actively engaged in both fundamental and clinical research studies. These experienced researchers not only conduct cutting-edge investigations but also serve as adept mentors, providing invaluable guidance to our fellows as they explore their research passions. Moreover, our fellows have the opportunity to expand their horizons by selecting primary research mentors from outside the division, broadening their exposure to diverse perspectives and methodologies.

As a robust teaching and research institution, the University of Washington School of Medicine (UWSOM) is home to the Kidney Research Institute (KRI), the highly ranked School of Public Health and many other research centers engaged in innovative investigation.

Our Pediatric Nephrology Fellowship Program places a strong emphasis on flexibility, catering to a diverse array of career options within the field. Offering two distinctive tracks – Academic and Clinical – our program ensures a comprehensive learning experience. Both tracks begin with a 6-month immersive experience, offering a comprehensive and in-depth introduction to the realm of pediatric nephrology. This foundation equips our fellows with the necessary insights to embark on their chosen trajectory starting from the latter half of the first year.

In addition to the primary tracks, we offer a series of pathways, that allow fellows to pursue a topic in more detail. Examples of pathways include transplant, dialysis, hypertension, glomerulonephritis, critical care nephrology, health equity, bioethics, quality improvement, medical education, and informatics.

Below, we present the composition of the two tracks across the three years of the fellowship training program, indicating the total duration of each activity in weeks. The flex blocks allow additional time for clinical or research activities.

Clinical Rotations

Clinical activities occur under the supervision of division faculty members who serve as inpatient and outpatient attending physicians on a rotating basis. The clinical year experience encompasses all aspects of clinical pediatric nephrology, including all modalities of renal replacement therapy (acute/chronic dialysis and renal transplantation). Inpatient rotations cover the primary nephrology service and the nephrology consult service for the ICUs (PICU/CICU/NICU), wards and emergency department. Outpatient care includes home or in-center chronic dialysis, renal transplant care, percutaneous renal biopsies, telephone consultations from outside providers and a dedicated fellows’ clinic. Fellows complete all rotations on site at Seattle Children’s Hospital, with opportunities to participate in prenatal consults and regional clinics offsite.

Research Months

The University of Washington has many cross-disciplinary and collaborative opportunities for research projects within and outside the division. Starting in the first year, fellows work with faculty to identify a research project and research mentors within the desired area of study. Research opportunities and mentors are available in a wide variety of areas, including basic, translational and clinical research. Coursework may be pursued, depending on the research topic, at the University of Washington School of Public Health.

Each fellow has a Scholarship Oversight Committee, composed of faculty mentors within and outside the division. The SOC meets regularly to provide structure and guidance for research and career planning. Fellows will typically present their work at one of the major national meetings, with travel support provided by the fellowship program.

Diversity Statement

We value providing our patients with culturally sensitive care.  We seek applicants that are dedicated to providing this care and encourage applicants from diverse backgrounds to apply. 

The University of Washington has pledged to fight and dismantle systemic racism within our institutions, our policies, and our practice of medicine. We are fortunate to have a number of outstanding resources for these tasks in our community, including the Center for Health Equity, Diversity and Inclusion, the Network of Underrepresented Residents and Fellows

Seattle Children's Center for Diversity and Health Equity is dedicated dedicated to reducing health disparities and improving the lives of all patients, families, research participants and the community. Our mission is to prioritize equity by advocating for and facilitating the relentless work toward the recognition and elimination of health inequities for children, families and communities, through an inclusive and anti-racist framework.

The Seattle Children’s Inclusion Network Program supports the organization’s commitments in the Health Equity and Anti-Racism Action Plan. Inclusion Networks are employee-led groups open to all Seattle Children’s workforce members that foster an inclusive culture where everyone belongs. Fellows are welcome to be a part of any of the Inclusion Networks (IN) among which are the Asian IN, Black and African IN, Disability IN, Hola IN, Pasifika IN, and Q Pod Network.
