Mathematical modeling and analysis of neurons and neural networks.
Office: Kolb Research Annex| 7th floor | Room 759
My research involves the mathematical modeling and analysis of neurons and neural networks. Analytic techniques and computer simulation are used to study how different conductances contribute to the electrical characteristics of a neuron, how neurons interact to produce functioning neural circuits, and how large populations of neurons represent, store, and process information.
