Our research has evolved over the years. Originally, we focused mainly on near-field scanning optical microscopy (tip-enhanced fluorescence microscopy in particular), with the goal to image nano-scale biological structures. With the emergence of far-field superresolution imaging techniques (e.g., STED, PALM, STORM, etc.), which are more suited to this purpose, we shifted to studying the interactions between light-fields and nanoscale structures. More recently, we have also gotten into the superresolution business, and have also developed a novel implementation of (diffraction-limited) scanning confocal hyperspectral imaging, which we are using to study GaN nanowires and semiconductor thin films.
