Research activities in the Ragan group lie on the boundary of fundamental and applied research of nanomaterials. A fundamental understanding of self-assembly is pursued as this is as a disruptive technology solution manufacturing nanosystems in device architectures. Systems investigated can impact technology from optical communication/sensing to energy systems. The Ragan group studies systems from the mesoscale to the atomic level.  Scanning probe microscopy and first principles calculations are important tools to understand thermodynamic driving forces in self-assembly and structure-function relationships. Understanding of how to both control of atomic and molecular structures and how this control affects physical properties is critical to optimize the performance of nanoscale devices. 

Research Topics: Self-assembly of hybrid organic/inorganic nanostructures for nanoscale electronic and sensing applications; correlating electron transport and optical properties with atomic and molecular structure.
