Long Bio
Steven M. Baer works in the area of mathematical and computational neuroscience. The goal of his neuroscience research program is to develop mathematical/computational tools to obtain new insights into the electro-chemical properties of individual neurons and their networks. At the network level his primary goal is to unravel the biophysical mechanisms of learning in the brain by exploring models of synaptic plasticity (the ability of synapses to strengthen or weaken over time). Another goal is to build a biophysically realistic continuum model of network activity in the retina. As an applied mathematician Baer works in the area of nonlinear dynamics; perturbation methods; bifurcation and stability. His research program is highly interdisciplinary with co-authors from biology, engineering, physics, and mathematics.
