Professional Background

My overall career goal is to help improve the care of children with neurologic disability. Early in my training I decided to focus on neurogenetics, as many causes of neurologic disorders in childhood have a genetic basis. After completion of my pediatrics and medical genetics training at the University of Connecticut, I then moved to St. Louis for child neurology training at Washington University. I see patients as part of the Neurogenetics Consultation Service and the Hereditary Ataxia Program.


The Paciorkowski Lab research program is focused on the discovery of genes involved in childhood neurologic disorders, and how those genes affect brain development. Currently, the lab is working on next-generation sequencing approaches to gene discovery in severe pediatric epilepsies such as infantile spasms. We are also studying complex developmental disorders where autistic features, intellectual disability, epilepsy, and movement disorders overlap. A key part of our research program is the creation of new bioinformatics tools to analyze and integrate data.
