Gregg A Swayze, Ph.D.

Research Interests

Over the years, Gregg has developed methods to spectrally map acid-mine drainage in Leadville, Colorado, naturally-occurring asbestos in the foothills of California, insulation asbestos in the World Trade Center dust, and oil emulsions formed during the 2010 BP oil spill. He has also developed a portable spectral fingerprinting technique to identify asbestos-bearing vermiculite in attic insulation. Gregg has used his imaging spectroscopy experience with relict hydrothermal systems in Nevada and Hawaii to help map similar mineral deposits on the surface of Mars with the NASA CRISM orbital spectrometer. His most recent focus is on spectrally mapping REE-bearing minerals at the Mt. Pass Mine in California. He was recently selected as a Co-Investigator of the NASA/JPL Earth Surface Mineral Dust Source Investigation (EMIT) team with the goal of putting an imaging spectrometer on the International Space Station to map the mineralogy of dust source regions on a global basis.
