Our research is at the nexus of nanotechnology and optics! We use light to excite single nanostructures (a few tens of nano-meters in dimensions!); and probe their interactions with light using optical spectroscopy. Currently, we are looking into the possibility of enhancement and control of "magnetic" light-matter interactions in high-index dielectric nanoparticles, metamaterials, rare earth ions, etc. For more details, see RESEARCH.
