One-Line Research Description

Applications of mathematics to biological systems

Dr. Ermentrout's research program investigates the dynamics of neural populations and neural rhythmicity. His recent focus has been on the behavior of networks of cortical-like neurons. He is interested in the wave propagation in cortical and thalamic slice models and how neurons synchronize and what the role of this synchronization might be. He applies methods from dynamical systems and pattern formation to a variety of neural problems. He has recently used computational and mathematical modeling to study correlation-induced synchrony in the olfactory bulb. His work spans the gamut from single cell and channel modeling through large scale models of behavior and to the development of neural connectivity. He is the author of XPPAUT, a software platform for the simulation and analysis of nonlinear dynamical systems that is also a popular tool for computational neuroscientists.
