Koray Aydin

Associate Professor of Electrical Engineering and Computer Science

Ph.D. in Physics, Bilkent University, 2008; B.S. in Physics, Bilkent University, 2002

Research Interests

Koray Aydin's research interests lie at the intersection of applied physics, electrical engineering, materials science and nanotechnology, with the main theme of nanophotonics. Our research efforts are focused towards understanding the interactions of light with nanoscale materials, designing optical metamaterials with novel electromagnetic and photonic properties, and integration of nanoscale photonic materials with devices for applications in energy, health care, defense and communications. We utilize analytical and numerical electromagnetic simulation techniques for the design, advanced nanofabrication methods for the fabrication, and nanoscale optical and electrical characterization tools for the characterization of nanophotonic materials and devices.
