Research Interests

My primary research interest is in understanding the relationship between interneuronal development and altered excitability that leads to epilepsy. This pattern is primarily seen in children with malformations of cortical development but also a number of emerging set of diseases called interneuronopathies. We are studying how loss of a gene important for interneuronal development, the gene ARX, can lead to changes in excitability and development of epilepsy. I am also interested in analyzing intracranial EEG recordings to learn how to better localized the epileptic zone and network. These studies will improve how patients are cared for during epilepsy surgery and improve the understanding of how abnormal brain generates seizures.
