Biography

Marc Imhoff began his career at NASA's Goddard Space Flight Center in 1980 as a Regional Applications Project Manager integrating remote sensing technology with the resource management activities of state governments. From 1983 to 1987, Imhoff moved to the Space Data and Computing Division and won a position on the science team of the Shuttle Imaging Radar-B (SIR-B) mission researching the use of vegetation penetration radar imaging systems to target malaria vector breeding habitats in the tropics. As a SIR-B science principal investigator Imhoff ran field campaigns in the Ganges - Brahmaputra Delta collecting data needed to develop radar-based methods for mapping flood boundaries, rice agriculture, and surface terrain elevations in flooded forests. During that time, Imhoff also worked on the Landsat-4 Data Quality Assessment Team and helped run a series of NASA/DoD technology transfer projects.

From 1987-1989, Imhoff served as an Instrument Manager with the Earth Observing System Project Office supporting the mission through its non-advocacy review. In 1990, Imhoff was awarded a Research and Study Fellowship to Stanford University. At Stanford, Imhoff developed methods for measuring forest structure and biomass using radar imaging and polarimetry for global carbon inventory, resource assessment, and terrain analysis. From the mid 1990's Dr. Imhoff continued to lead numerous research and development projects. He developed the first civilian long wavelength (VHF) radar sensor to penetrate vegetation and soils, and worked with both the Department of Energy and the Defense Advance Research Projects Agency on foliage penetration radar technology and applications. As an EOS Interdisciplinary Science Team Member Dr. Imhoff worked on the use of multisensor technology for the remote detection of human settlements and the impact of human driven land cover change on biological productivity and agriculture. Imhoff was co-creator of the nighttime ‘city lights' images of global urbanization from the DMSP/OLS sensor and developed one the first satellite-based indicators for assessing the strategic vulnerabilities of populations to climate change and food production. From 2001-2004 he served as the Earth System Science Pathfinder Program Project Scientist (ESSP) where he had an executive role in developing the solicitation, reviewing proposals, and recommending the selection of new missions.

From 2005 to September 2012 Dr. Imhoff was the Project Scientist for Terra - an active on-orbit satellite mission consisting of five instruments and science teams covering seven Earth system science research focus areas. Imhoff was chair of the mission science team and was responsible for justifying mission continuation and managing the annual budget required for flight operations and science team activities.

Dr. Imhoff is the Interim Director of PNNL's Joint Global Change Research Institute in College Park, MD.
