Director of Personalized Care, Pathology and Laboratory Medicine
Attending Physician
Professor of Pathology and Pediatrics (Clinical Scholar), Keck School of Medicine of USC

Dr. Deardorff studies syndromic disorders that involve intellectual disability. His goal is to develop tools to better understand the effect of genetic changes in children who have these conditions and to identify a strategy for medical intervention. He is pursuing this goal in both the lab and the clinic.
