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,
2) characterization of photoacids in chemically amplified photoresist,
3) fluorescence imaging in biomedical engineering,
4) instrumentation.
