Paul Haney

Paul Haney is a Project Leader in the Energy Research Group in the CNST. He received a B.S. in Physics and Mathematics from The Ohio State University, and a Ph.D. in Physics from The University of Texas at Austin. His thesis focused on first-principles calculations of electron and spin transport in magnetic and antiferromagnetic multilayers. Paul spent two years as an NRC Postdoctoral Research Associate in the CNST Electron Physics Group, where he worked with Mark Stiles on the theory of spin transfer torque in magnetic semiconductors and in materials near their Curie temperature. He joined the Energy Research Group in 2009. Paul’s current research includes the effects of disorder in materials used for renewable energy, specifically applied to organic photovoltaics and thermoelectrics.
