Description of Clinical Expertise
1c6 Dr. Ellis is a neurologist with expertise in the management of seizures and epilepsy. This includes expertise in EEG, anti-seizure medications, surgical treatment of epilepsy, neurostimulation, and implantable devices. Dr. Ellis also has clinical expertise in genetics and the genetic causes of epilepsy. He sees patients with epilepsy for genetic evaluations at the University of Pennsylvania and the Children's Hospital of Philadelphia.71
Description of Research Expertise
183 Dr. Ellis's research is focused on the genetic basis of epilepsy. He is particularly interested in the discovery of genes that cause epilepsy; the heritability of epilepsy within families; and the use of genetics to improve the diagnosis and treatment of epilepsy. An additional research focus in the mining of electronic health records using natural language processing.e 29
