Department of Pediatrics

Nephrology Fellowship

Mission Statement

To train and produce physician-scientists in basic science and clinical research, to become leaders in the field of academic and clinical pediatric nephrology.

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.

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:

Russell Whelan, MD, PhD (2017-2020) (4th year Research Fellow 2020-2021)

Research Mentors: Dr. Ying Zheng and Dr. Jonathan Himmelfarb

Dr. Whelan has been studying on the role of vascular injury in engineered microvessels, with a particular focus on Shigatoxin-mediated vascular injury.  His work this year will focus on (1) optimizing and using engineered microvessels to recapitulate the endothelial injury and thrombotic microangiopathy seen with Shigatoxin-mediated illnesses, and (2) further elucidate the underlying pathologic mechanisms in Shigatoxin-mediated illnesses. 

Elizabeth Nguyen, MD, PhD (2018-2021)

Research Mentors: Dr. Mark Majesky, Dr. David Beier

Dr. Nguyen is interested in understanding the cellular response to acute and chronic renal injury. She will be working in the lab of Dr. Mark Majesky and investigating the mechanism of scar-free renal tissue repair in response to injury as demonstrated by the African spiny mouse.

Alexander Kula, MD (2018-2021)

Research Mentors: Dr. Nisha Bansal, Dr. Yuk Law, Dr. Sangeeta Hingorani

Dr. Kula is interested in the pathologic mechanisms connecting the kidney and heart in both primary renal and cardiac disease. He will be working to describe the epidemiology of heart disease in children and young adults with chronic kidney disease (CKD) and more specifically, he will focus on less described phenotypes of cardiac disease in pediatric CKD such as diastolic dysfunction and chronic, subclinical ischemia.

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.
