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:
1) characterization of semiconductor nanostructures, for example, GaAs, GaN.
2) characterization of photoacids in chemically amplified photoresist.
3) fluorescence imaging in biomedical engineering,
4) instrumentation.
