Our laboratory emphasizes the combined use of optical spectroscopy and optical imaging as a tool for materials characterization. The primary spectroscopic techniques we employ are photoluminescence, photoluminescence excitation, and molecular fluorescence. The optical techniques we use include traditional far-field microscopy, confocal microscopy, interferometry, and near-field optics.

We maintain four main areas of focus: 
l characterization of semiconductor nanostructures, 
l characterization of photoacids in chemically active photoresist,  
l fluorescence imaging in biomedical engineering, and 
l instrumentation.
