Program Manager: Lawrence Freidl, NASA-Headquarters

Lawrence Friedl serves as Program Manager for several NASA programs. He leads the efforts in the applications areas of Air Quality and Coastal Management, and to apply NASA's Earth Science data and technology to support policy and management. Friedl joined NASA in April 2002. Prior to this, Friedl served as a Special Assistant in the U.S. Environmental Protection Agency's Office of Research and Development, focusing on applications of geospatial data and technology. He was also the Program Coordinator for EPA's Advanced Measurement Initiative. Friedl has also served as a Space Shuttle Flight Controller in NASA's Mission Control Center before turning his attention to the policy applications of remote sensing. Friedl received an Aerospace Engineering degree from Princeton University, and a M.S. in Public Policy from Harvard University's Kennedy School of Government.


Deputy Program Manager: Jared Entin, NASA-Headquarters

Jared Entin graduated from the University of Maryland with a Ph.D. in Meteorology. He studied the spatial and temporal scales of soil moisture, as well as worked on validation efforts for numerous land surface models through the GEWEX Global Soil Wetness Project. In 1999, Entin started working at the NASA-GSFC Hydrological Processes Branch, where he joined Dr. Paul Houser on the LDAS project in an effort to use TRMM radiometer data to determine soil moisture, and subsequently infuse that information into a land surface model using data assimilation techniques. In 2002, Entin moved to NASA-HQ to manage the Terrestrial Hydrology program, as well as to help guide NASA's efforts in the Global Water and Energy Cycle field. As of mid-2002, the Earth Sciences Enterprise Applications division at NASA-HQ has initiated twelve national applications. Dr. Entin is helping to direct one of these, the Water Management and Conservation application.


Deputy Program Manager: David Toll, NASA-GSFC

David Toll is active in the research and application of hydrology, microclimatology, and environmental science using remote sensing systems. David Toll has a B.S. in Natural Resources (Wildlife Biology) from Colorado State University (1976), a M.S. in Earth Resources (Remote Sensing) from Colorado State University (1978), and a M.S. in Geography (Microclimatology) from the University of Maryland (1991). He worked in the NASA/GSFC Biospherics Branch from 1978-1988, conducting research on remote sensing of biophysical parameters using primarily optical and thermal infrared systems. He has worked in the GSFC Hydrological Sciences Branch since 1988. Specific areas of interest include the application and improvement of the modeling and remote sensing of land surface water and energy fluxes, and the application of remote sensing technology for water resources applications. He currently is the NASA Deputy Program Manager in Water Management and helps lead projects with the EPA and the Bureau of Reclamation.
