David Gallaher

Senior Associate Scientist

Degrees: 

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

Specialties: 

Big Data analytics, satellite remote sensing, spatial-temporal information systems, large scale database integration, raster and vector GIS, satellite system development, production data systems, data center energy efficiency, contract administration, organizational structures, work plans, project management, prioritization methodologies, and IT best practices.

Projects: 
  • Principle Investigator on the classified ICARTA and BEADS project dealing with finding new unconventional uses for military satellite assets.
  • Chief Data Scientist for Orbital Micro Systems (OMS), a partly University of Colorado owned corporation. OMS is currently sending up 48 passive microwave sounders for climate, aviation, agriculture, insurance and military uses. He is also the manger of the OMS International Center for Earth Data (ICED)
  • Project Manager and Co-Investigator on an NSF grant for a project to design and prototype a process (through creation of a condensate database "Data Rods") for addressing time-series data as pure objects that will enable time-centric change analysis of massive remote sensing data.
  • Principal Investigator on a project to recover Nimbus satellite data from the 1960s to determine the sea ice extent during that decade.
  • Part of the team building a low-cost CubeSat “GEMS,” a 118GHz Passive microwave satellite to monitor polar ice and atmospheric conditions.
  • Award winning  “Green Data Center” at NSIDC that reduced the power consumption for cooling by 90 percent and total energy use by more than 70 percent.
