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 fellowship program is designed to train academic pediatric nephrologists committed to careers with significant teaching and research activities. Each fellow works with the faculty to design an individualized research program in basic science, clinical research or translational investigation. Members of the division engage in basic or clinical research studies and have considerable experience as research supervisors, in addition fellows may select primary research mentors outside the division. 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.

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 University of Washington Center for Health Equity, Diversity and Inclusion, the Network of Underrepresented Residents and Fellows, the Seattle Children's Center for Diversity and Health Equity, and Dr. Jason Deen, the Department of Pediatrics Associate Vice Chair for Equity, Diversity and Inclusion.

Clinical Year

Fellows typically begin their training with the clinical year. 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 Years

The research component of the fellowship program is typically two consecutive years. 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.

Research Projects of Current Fellows:

Elizabeth Yu, MD (2018-2021)

Research Mentors: Dr. Jodi Smith, Dr. Shina Menon, Dr. Kirk Liesemer

Dr. Yu is interested in improving systems based care of the complex medical child with renal disease. She is currently working on utilizing the North American Pediatric Renal Trials and Collaborative Series (NAPRTCS) dataset to describe the clinical characteristics and survival of infants on hemodialysis compared to their counterparts on peritoneal dialysis. She also is beginning to explore ideas for quality improvement, and would like to improve the vaccination rates of children with late stage chronic kidney disease.

Taylor House, MD (2019-2022)

Research Mentors: Dr. Abby Rosenberg, Dr. Susan Wong, Dr. Aaron Wightman

Dr. House aspires to be a leader at the intersection of pediatric nephrology and palliative care, she is interested in investigating, understanding, and improving the communication that takes place with parents and patients regarding initiation, withholding, and withdrawal of renal replacement therapy.

Reya Mokiao, MD (2019-2022)

Research Mentors: Dr. Jason Deen, Dr. Bessie Young, Amanda Fretts, Dr. Sangeeta Hingorani

Dr. Mokiao is interested in social determinants of health such as food insecurity, housing status and its associations with renal outcomes. She is also interested in indigenous population health including American Indians, Alaskan Natives, Native Hawaiians and Pacific Islanders. Her research will explore associations between dietary quality as a proxy for food insecurity and renal outcomes using data from the Strong Heart Study.

Machi Kaneko, MD (2020-2023)

Research Mentors:

Jacob Little, MD (2020-2023)

Research Mentors: Dr. Shina Menon, Dr. Jodi Smith, Dr. Gerry Zimmerman, Dr. Reid Farris
