The primary goal of Tim Lewis’ research is to understand how intrinsic properties of neurons and the connectivity between neurons give rise to activity observed in neuronal networks. In doing so, he hopes to provide insight into the functions and dysfunctions of neural systems. He combines mathematical analysis of idealized models with numerical simulations of more biophysically realistic models. The idealized models help to uncover the basic mechanisms underlying the neural activity, whereas the biophysical models allow for direct comparison to experimental data. Collaboration with experimentalists is an essential part of his work.
