Dr. Ferree earned his B.S. degree in Physics in 1986 from the University of Florida, and his Ph.D. in Physics in 1992 from the University of Colorado, specializing in relativistic quantum field theory and numerical computation. He spent three years as an NIH postdoctoral research fellow at the University of Oregon Institute of Neuroscience. He is currently a Scientist at Electrical Geodesics and Courtesy Research Associate in the Computational Science Institute at the University of Oregon. His current research addresses the physics of EEG and MEG, inverse problems in tissue conductivity estimation and brain source localization, and nonlinear time series analysis for assessing ischemic stroke. His more basic research interests are in population models of human cortical tissue and the use of high-density EEG and MEG to constrain and discriminate among such models. problems and have substantially benefited
