My research interests focus on applications of scattering and reflectance measurements, advanced light sources, and robotics to the characterization and metrology of optical materials.  I am the project lead on ROSI (the Robotic Optical Scatter Instrument), a new NIST facility for ultraviolet to shortwave infrared spectral- and angle-resolved reflectance and scattering measurements.
