Nephrology and Hypertension

An interdisciplinary team caring for children with acute and chronic kidney disease

Members of the Division of Nephrology and Hypertension provide compassionate state-of-the-art care for patients with acute and chronic kidney disease. Our division is at the forefront of research and discoveries that advance our understanding of kidney disease and its prevention, diagnosis, and treatment and train physicians in the best practices in pediatric nephrology.

Clinical Services

The division has five full-time and one part-time faculty members and provides comprehensive care for a wide range of kidney conditions. We have designated medical directors for our dialysis program and kidney transplantation program. The division’s dedicated interdisciplinary team includes physicians, a nurse, a nurse practitioner, a medical assistant, a dietitian, and a social worker who are all fully committed to caring for children with kidney disease and supporting them and their families through education and other resources.


The division currently receives NIH funding for basic science, clinical, and translational research. Our broad research areas encompass cell biology of kidney tubular response to ischemic injury or urinary tract obstruction, pathogenesis of acute kidney injury and chronic kidney disease, observational studies in glomerular disease, gene discoveries for congenital anomalies of the kidney and urology tract, and genetic studies for chronic kidney disease. We have ongoing and fruitful collaborations with precision medicine, adult nephrology, pathology, and neonatology that are providing knowledge that will serve as the basis of future therapies for kidney disease.


The division is heavily invested in educating future generations of pediatricians and pediatric nephrologists. Since 2012 we have been one of the most popular subspecialties for medical student and resident rotations. Over the past five years, two of our fellows were named Fellow of the Year and one faculty member was voted Attending of the Year by pediatric residents at Columbia University Irving Medical Center (CUIMC). Through the Nephrology Fellowship program, we train pediatric nephrologists to achieve high competence in patient care, renal research, and education. The program emphasizes hands-on learning and didactic teaching, and through a rigorous curriculum, fellows learn to diagnose and treat children with a wide spectrum of acute and chronic kidney diseases.

New Appointments

New Programs

Pediatric to Adult Transition Clinic (2019) by Hilda Fernandez, MD, a board-certified nephrologist in both pediatric and adult kidney care at the medical center, provides seamless transition for continuous care from pediatric to adult renal service. Dr. Fernandez teaches adolescents the knowledge and skills to care for their own kidney conditions and prepare their families for this transition.

CUIMC Hypertension Program (2020), part of the Hypertension Center at CUIMC. Working closely with several subspecialties in the adult and pediatric services, we combine the most advanced technologies in hypertension diagnosis with a personalized treatment and care plan for our children and their families.

Patient Spotlight: Sakeenah and Siraj Wadood

Sakeenah Wadood was five months pregnant when her obstetrician in Sullivan County, NY told her that her baby boy might only live for a matter of minutes. A prenatal ultrasound had shown that his kidneys were enlarged, and that Sakeenah’s amniotic fluid levels were low. Optimal levels of amniotic fluid are crucial for fetal lung development, and her doctor was concerned that the baby’s lungs would not develop properly and that he wouldn’t be able to breathe on his own. His enlarged kidneys also signaled a serious abnormality in his urinary tract.

Lin Lab

Two women smile together in a lab.

Research in the Lin Lab is focused on understanding the pathogenesis of acute kidney injury (AKI) and the transition of AKI to chronic kidney disease (CKD). We take the approaches of cell and molecular biology, renal pathophysiology, and mouse genetics to understand kidney tubular stress response to ischemic injury and metabolic perturbation.
