Assistant Professor
Pediatrics | Children’s Medical Center Research Institute at UT Southwestern

Dr. Izumi obtained his MD and PhD at Keio University School of Medicine, where he studied molecular mechanism of pediatric genetic disorders.  He completed clinical pediatrics and genetics training at Rainbow Babies and Children’s Hospital and the Children’s Hospital of Philadelphia. He achieved board certification in pediatrics and medical genetics. After the clinical training, he became a post-doc at the Children’s Hospital of Philadelphia and the University of Tokyo. During his post-doc training, he investigated molecular mechanism of a chromosomal disorder, Pallister-Killian syndrome, and syndromic neurodevelopmental disorders. Prior to joining the University of Texas Southwestern, he was a faculty member of the Children’s Hospital of Philadelphia. In 2023, he joined the Department of Pediatrics, University of Texas Southwestern. His research lab has focused on projects studying the molecular mechanisms of Pallister-Killian Syndrome, nuclear speckle disorders, and chromatin disorders. His group discovered causative genes for many Mendelian disorders, and those include AFF4, ARCN1, NKAP, and CBX1. By employing cutting-edge genomic technologies, his research aims to link the clinical findings of patients with genetic disorders to underlying genomic functional alterations.
