Amar Nijagal, MD

Pediatric surgeon

Dr. Amar Nijagal is a pediatric surgeon who specializes in caring for children with disorders of the liver and bile ducts.

Nijagal runs a research lab that investigates how the immune system affects the development of fetal organs. His research focuses on liver and bile duct development and how changes in the process contribute to congenital diseases.

Nijagal completed his medical degree and a residency in general surgery at UCSF, where he served as chief resident. He completed a postdoctoral research fellowship at the California Institute for Regenerative Medicine and a fellowship in general and thoracic pediatric surgery at Boston Children's Hospital.

Nijagal is a member of the American College of Surgeons, American Pediatric Surgical Association, UCSF Naffziger Surgical Society and Association for Academic Surgery.
