Research Interest

When light interacts with matter over a nanometer scale the behavior can be considerably different than what one finds in macroscopic scales – the optical properties of materials and their response to light can change depending on the specific geometry. By creating artificial structures we can achieve complex materials with new properties and to control the interaction of light and matter. In my research I focus on several aspects of this theme, which combine chemistry with optics, quantum physics and material science:
  1. Strong interaction of molecules with light - I investigate the optical properties of organic molecules (dyes) coupled to optical devices, aiming toward understanding quantum many-body processes in such hybrid systems and controlling these interactions. Gaining such control is important for photo-chemistry, light-harvesting and organic light-emitting devices.
  2. Optical properties of metallic nanoparticle-clusters - A nanometer-size gold particle has a very distinct color, completely different than the color of bulk gold. The reason is that when we shape a metal over a nanometric scale it supports localized plasmon modes that depend on details such as geometry and size. In my research I explore the assembly of such nanoparticles into well-defined clusters in order to achieve composite materials with new optical properties.
