Welcome to My Site


We investigate the properties of light beyond the diffraction limit and study its interaction with nanoscale matter. We are particularly interested in interrogating single quantum systems and in exploring quantum phenomena that occur at the subwavelength scale. Although we primarily address fundamental questions related to light, matter and their interaction, our efforts may also make their way into practical devices, such as a new class of light-sources, sensors and functional materials.
