Lisa Gaddis is a Research Geologist with the Astrogeology Science Center of the U.S. Geological Survey in Flagstaff, AZ, where she has worked since 1990 as a scientist and an administrator. Lisa served as Chief Scientist of Astrogeology from June 2003 to October 2007. Her research interests focus on the use of remote sensing data at multiple wavelengths to understand geologic processes on the surfaces of Earth, Moon, Mars, and Venus.
Lisa has expertise in planetary science, cartography, data archiving and mission operations. In addition to being experienced in the use of radar data for characterizing emplacement and evolution of volcanic and eolian terrains on Earth, Lisa is skilled in calibration and analyses of spectroscopic data from visible/near-infrared and thermal emission systems. Her research projects have included field studies of Kilauea Volcano and Pisgah lava flow in California to understand how volcanic deposits are represented in remote sensing data, use of visible and near-infrared Clementine multispectral and Kaguya Multiband Imager data for compositional studies of volcanoes on the Moon, deconvolution of thermal emission data from Mars Global Surveyor to study the origin of layered deposits in channels, canyons, and craters on Mars, and use of stereo image data to characterize pyroclastic deposits volumes and morphology at the lunar crater Alphonsus.
Lisa has long been involved cartography research in Astrogeology and in particular she served as Science Lead for an Astrogeology planetary cartography project to digitize, process, and create a long-lasting and valuable digital archive of the Lunar Orbiter photographic data from the late 1960's (Lunar Orbiter Digitization Project). In partnership with staff at USGS and JPL, Lisa is Principal Investigator for the Imaging Node of the NASA Planetary Data System, which currently manages ~400 TB of image and ancillary data from 20 planetary missions. In addition to supporting several active mission archiving efforts and data nodes for MRO HiRISE, THEMIS and LROC teams, the Imaging Node team has developed and released products such as the Clementine Ultraviolet-Visible and Near-Infrared Global Mosaics of the Moon, the Lunar Orbiter global and frame mosaics, Apollo Rock Sample Images (JSC, for PI Gary Lofgren), and is now preparing the PDS-compliant archive of photos (scanned at the Johnson Space Center under the auspices of Dr. Mark Robinson at Arizona State University) from the Apollo Metric, Panoramic and Handheld cameras.

Service
Dr. Gaddis is an active member of NASA review and advisory panels for space science, space exploration, and planetary cartography. She has convened research and planetary data workshops and is actively involved in national and international research collaborations, workshops and meetings. Lisa served as Editor for the Planetary Sciences Section of Eos, Transactions of the American Geophysical Union. Currently a Consulting Member of the Working Group for Planetary System Nomenclature of the International Astronomical Union (Gazeteer of Planetary Nomenclature), Gaddis also has served as Chair of the Science Council of the Lunar and Planetary Institute of the Universities Space Research Association (USRA, http://www.usra.edu/). IN 2012, Lisa was appointed as a member of the Planetary Sciences Subcommittee of the NASA Advisory Council (NAC) Science Committee.
Education & Public Outreach
As do many Astrogeology scientists and staff, Dr. Gaddis frequently gives public presentations on research topics in earth and planetary science. She particularly enjoys speaking and working with children of all ages, and she gives in-class talks, provides tours of USGS facilities, and serves as judge in local science fairs.
