A nationally-recognized expert in pediatric hematology, Dr. Nugent’s clinical and research interests include blood disorders, bone marrow failure, bleeding and clotting disorders, and white cell and immune deficiencies. She is involved in a number of clinical trials for rare blood disorders, including a study that looks at the use of Fibrogammin P, a human plasma derived Factor XIII concentrate, in patients with congenital Factor XIII deficiency. Dr. Nugent is also principal investigator for the Region IX MCHB Hemophilia Treatment Program and its associated research.
A prolific author on innovative medicine, Dr. Nugent has coauthored more than 100 journal articles and book chapters and has been featured in journals including Haemophilia, Blood, New England Journal of Medicine, Thrombosis Research and more. She specializes in all aspects of hematology, bone marrow failure, anemias, immune disorders, bleeding and clotting disorders. Specialized procedures include bone marrow biopsy, aspiration and lumbar puncture.
Dedicated to clinical excellence, Dr. Nugent is board certified in both pediatrics and pediatric hematology-oncology. Prior to joining CHOC Children’s, Dr. Nugent attended medical school at the University of California, Los Angeles. Her residency and internship training were completed at Denver Affiliated Hospitals in Colorado. Dr. Nugent received her fellowship training at Children’s Hospital Medical Center in Seattle and Fred Hutchinson Cancer Research Center.
A respected physician leader, Dr. Nugent was recognized as Physician of the Year in Orange County and serves as chair of review subcommittees at NHLB1/NIH and HRSA Region IX program projects in the area of hematology. Dr. Nugent speaks fluent Spanish.
