Research Interests

Infrared
My group studies materials by optical reflectance or transmittance at wavelengths from the far infrared through the near ultraviolet. Among the topics being studied are high-temperature superconductors, conducting polymers, and low-dimensional organic systems. We also are members of U12IR at the NSLS, where we do pump-probe measurements in the far infrared, in collaboration with Larry Carr and Dave Reitze.

LIGO
The Laser Interferometer Gravitational-wave Observatory (LIGO) project is constructing interferometers at Hanford WA and Livingston LA for detecting gravitational waves from astronomical sources. The UF LIGO group is building the input optics for LIGO and studying advanced configurations for the LIGO detector.

Axions
With Pierre Sikivie and Neil Sullivan, I'm involved in a full-scale dark-matter axion search at Lawrence Livermore National Laboratory. The Florida group contributed a high-resolution spectral analysis package to this experiment.
