Our research program broadly studies the interaction between light and nanostructured materials, and particularly focuses on the emergent optical, electrical, and chemical properties of nanoscale materials under light concentration. By tailoring the nanoscale geometry, environment, and complex dielectric function we control the propagation of light in subwavelength dimensions, creating new materials not found in nature and improving our fundamental understanding of light absorption, emission, and carrier collection. We are especially interested in studying plasmonic materials, colloidal nanoparticles, and metamaterials, in addition to their interactions with atoms, molecules, and semiconductors. We design nanostructures using a combination of experimental and theoretical techniques, synthesize our structures using both bottom-up and top-down methods, characterize the electrical and optical properties, and ultimately integrate our designs into functional devices and systems. Our research is highly interdisciplinary and combines principles from physics, chemistry, materials science, chemical engineering, and electrical engineering. Our current research interests include: (1) improving the efficiency and reducing the cost of solar cells through nanophotonic design, (2) designing chiral materials.
