My research focuses on the development of new functional materials with controlled chemical and physical properties for applications in a range of technological areas from energy to environmental and information technologies. Of particular interest are solar energy conversion devices, energy storage devices, light emitting devices, transistors and sensors. The research activities involve material synthesis and characterization, device fabrication and testing, and theoretical computation and simulation. Materials of interest range from organics to metallo-organics, polymers, and organic/inorganic hybrids. The major purpose of the research is to study the underlying chemical and physical properties of new materials, and understand how molecular structure and processing conditions control the material properties and affect their performance in devices. The end of the research is fundamental knowledge of the structure-property-processing-performance relationships that allows for the further development of materials and devices with desired properties and performance.
