Dr. Alberding is a research chemist for the Remote Sensing Group in the Sensor Science Division of the Physical Measurement Laboratory at NIST. His current research interests involve development of advanced methodologies for calibration and characterization of on-orbit and ground-based remote sensing systems, using laser-based sources. He is a member of the SIRCUS (Spectral Irradiance and Radiance Calibrations using Uniform Sources) laboratory and participates in the radiometric calibration of various instruments used in remote sensing. He is also involved with the project for Infrared Optical Properties of Materials and Components, performing calibrations of reflectance and transmittance of various materials using Fourier Transform Spectroscopy.
