David Gallaher

Manager, Technical Services


M.S., Northern Arizona University, 1984
B.S., University of Illinois, 1979


New system architectures, spatial-temporal information systems, large scale database integration, raster and vector GIS, document management systems, SOA architectures, web content management systems, object databases, contract administration, organizational structures, work plans, project management, prioritization methodologies, and IT best practices.


He is currently developing a "green data center" at NSIDC with the goal of reducing the power consumption for cooling by 95%. Dave is the lead investigator on an NSF grant for project to design and prototype a process (through creation of "Data Rods") for addressing time-series data as pure objects that will enable time-centric change analysis of massive multi-modality cryospheric data. He is also the Project Manager on a project to build web services and analysis application for determining changes to the Greenland ice sheet. His latest project is to recover 1960s Nimbus satellite data to determine the sea ice extent during that decade.
