Associate Professor, Materials Science and Engineering
Prof. Ullal's research interests are related to polymers, unconventional nanolithography, and optics. A current emphasis of his work is the imaging and patterning of 3D nanostructured polymers via superresolution optics, which circumvents the diffraction barrier and achieves nanoscale resolutions while using visible light and far-field optics.
