Dr. David A. Santek is a Scientist and Program Manager at the Space Science and Engineering Center (SSEC), University of Wisconsin–Madison. He holds a Ph.D. in Atmospheric and Oceanic Sciences (2007) and an M.S. in Meteorology (1978) from UW–Madison, and a B.S. in Atmospheric and Oceanic Sciences from the University of Michigan (1975). Dr. Santek has spent his entire professional career at SSEC, progressing from Science Applications Developer, Software Development Manager, Program Manager/Researcher, and Scientist. His work spans satellite data visualization, product development, data ingest systems, numerical weather prediction impacts, and the development of innovative satellite-derived wind retrieval techniques. He is the Principal Investigator (PI) and development manager of the Man computer Interactive Data Access System (McIDAS), a globally used weather satellite visualization and analysis system. Dr. Santek has led many NASA and NOAA projects on polar-orbiting and geostationary satellite-derived winds, including long-term reprocessed datasets used in NASA/GMAO and ECMWF reanalyses, and blended 3D wind products. His work has directly supported operational use of satellite-derived winds at NWP centers worldwide, including NCEP, ECMWF, NASA/GMAO, the U.S. Navy, and the UK Met Office.
