Esther Krook-Magnuson, PhD

McKnight Land-Grant Assistant Professor, Department of Neuroscience, University of Minnesota

Dr. Krook-Magnuson is an Assistant Professor at the University of Minnesota in the Department of Neuroscience.  During her postdoctoral research in the lab of Ivan Soltesz, Dr. Krook-Magnuson helped develop and successfully implemented on-demand optogenetic approaches for inhibiting seizures in a mouse model of temporal lobe epilepsy.  Her current work extends these methods to better understand the disorder and identify novel therapeutic strategies.

Research Interests

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.
