Research  
Dr. Ermentrout's research program investigates models of neural and muscle physiology. His recent focus has been on the behavior of networks of cortical-like neurons. He is interested in the dynamics of wave propagation in cortical and thalamic slice models, the olfactory lobe of the Limax, and the synchronization of cortical networks. He continues to be interested in spatial and temporal patterns in neuronal networks such as those observed during flicker stimulation and localized patterns of working memory. He also studies the effects of various ionic current and synaptic plasticity on the interactions between neural oscillators. He is the author of XPPAUT, a software platform for the simulation and analysis of nonlinear dynamical systems.

Graduate students:     Stephanie Hoogendoorn, Pranay Goel, Rodica Curtu, Jon Drover, Fatma Gurel, Jason Joy.

I have supervised undergraduate research projects for close to 20 students. If you are interested in applications of mathematics to biology and neurophysiology, then do stop by!
