General research interests in the field of fiber optics. Specifically, the development of specialty fiber optics for use in the delivery of laser power in surgical and industrial applications and for use as chemical and temperature fiber optic sensors. These specialty fibers include hollow glass and plastic waveguides and solid core, single-crystal oxide fibers. The hollow core waveguides are an excellent choice for the transmission of CO2 and Er:YAG laser energy and both hollow and solid core fibers are useful as fiber links in spectroscopic and thermometric applications aimed at the identification of chemical species and the measurement of low and high (>1500°C) temperature radiation.
