Research efforts in our group revolve around using lasers to initiate and study chemistry. A variety of lasers are employed to investigate problems in areas ranging from gas-phase Doppler spectroscopy to laser-assisted thin-film growth. Mass spectrometers are used extensively for product detection, but materials characterization methods such as x-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) are enjoying increasing popularity within our group.
