Research

Research Summary/Interests

Selective Neuromodulation

Neuronal networks, diversity, and specificity of function are important to both physiological processes and neurological disorders, including epilepsy. My laboratory seeks to improve our understanding of how cells interact within a network, how networks interact with each other, and the physiological roles of neuronal populations. In this regard, key questions remain in epilepsy research, including what are the principal networks, conditions, and cell types involved in initiating, sustaining, propagating, terminating, and potentially suppressing, seizures. By improving our understanding of these, we improve the prospects of someday reaching the goal of no seizures, no side effects, for all epilepsy patients. My lab uses rodent models of neurological disorders, including temporal lobe epilepsy, and techniques including electrophysiology, optogenetics, immunocytochemistry, transgenic animals, and behavioral experiments to address these fundamental questions
