Danny Miller is a Pediatrics/Medical Genetics resident at Seattle Children’s Hospital and the University of Washington. He completed his MD at the University of Kansas and his PhD work in the laboratory of Scott Hawley at the Stowers Institute for Medical Research. His PhD research focused on using next-generation sequencing technologies to identify genetic changes that occur during meiosis in the model organism Drosophila melanogaster as well as understanding how genomic structural variation altered the repair of double strand breaks during meiosis. He has a long-standing interest in long-read sequencing and how it may be used to identify and understand genetic changes that lead to human disease. As a child of deaf parents, Danny’s interest in human genetics and rare diseases started early in life, by constantly wondering why he could hear but his parents could not.
