- Associate Professor
Welcome. I am a physics professor working at the Krasnow Institute for advanced study at George Mason University. This webpage is designed to provide information for students in my classes as well anyone interested in learning about our research. Briefly, we perform numerical and experimental studies focused on both the physics of neuronal behavior as well as the physics of simple non-equilibrium systems. I hope you find this site useful and informative. Please feel free to contact me or my students if you have any questions or comments.
My research has focused on investigating dynamical structures in driven systems with a specific interest in their role in the functions of the brain. Transient but long-lived correlated dynamics underlie innumerable biological processes, from the lifecycle of an organism to conscious thought and social behavior. Transient dynamical structures are also the hallmark of a number of natural phenomena including tornados, hurricanes, gyres, and von Karman vortex streets, simple fluid systems that can support coherent structures.
