Dr. Gorden Videen is a research scientist at the Space Science Institute and adjunct faculty member at Texas A&M University. He also has worked on optical characterization of aerosols for the Army Research Laboratory and worked as a Program Manager in Atmospheric Science at the Army Research Office. He has been a Visiting Scientist at the University of Amsterdam, Univerisdad de Cantabria and Kyung Hee University. His background is in optics and he has performed experimental, theoretical, and modeling work investigating polarimetric light scattering and remote sensing of complex systems ranging from atmospheric aerosols and cometary comae to extended regolith systems. Many of these works have focused on obtaining information from the polarization and light-scattering properties of the systems, including the lunar regolith.
