Louie, Ray

Dr. Louie started at the Greenwood Genetic Center as a fellow in the Molecular Diagnostic Laboratory in 2014. After fellowship, he worked as an exome analyst for Greenwood Genetic Center and GeneDx. In 2018 Dr. Louie was promoted to Assistant Director of the Molecular Diagnostic Lab at GGC, and he became Associate Director in 2021. His background is in large-scale genetic screening in model organisms and in solid tumor genetics and radiobiology. Dr. Louie is interested in the diagnosis of Mendelian disorders and in the identification of novel genes involved in neurodevelopmental delay and hydrops fetalis.

Dr. Louie is board certified by the American Board of Medical Genetics and is a Fellow of the American College of Medical Genetics. He is also a member of the American Society of Human Genetics.
