Group Mission

We are dedicated to an interdisciplinary approach towards research that bridges the areas of nanoscale photonics, nanostructured materials, and plasmonics as well as their potential applications in optoelectronics and the biological sciences. The research topics transcend the boundaries of traditional disciplines and are typically a combination of fundamental science exploration, engineering design and optimization, device fabrication and characterization, and various applications.
