Brief Bio
After receiving his Ph.D, Steve Snowden worked for half a year on the Diffuse X-ray Spectrometer, a shuttle attached payload of the University of Wisconsin Space Physics Laboratory. After that he spent five and a half years at the Max Planck Institute for Extraterrestrial Physics in Germany, working on the ROSAT project, primarily on the soft X-ray diffuse background from the all-sky survey. Steve joined the USRSDC at GSFC in 1993 August, where he worked until 1998 when he took the position of lead scientist for the XMM GOF. In 2005 Steve became the Deputy Project Manager and Technical Officer for the NASA part of the XMM-Newton project. In 2009 Steve became the Project Scientist.
Steve's primary responsibility at GSFC is science support for the XMM Guest Observer Facility. This includes support for the US XMM users community from the proposal process to the analysis of XMM data.
Positions/Employment
Education
Steve received his BS in Mathematics, Physics, and Astronomy in 1978 from the University of Washington, his MS in physics in 1979 and PhD in physics in 1986 from the University of Wisconsin - Madison. The title of Steve's thesis is: Neutral Hydrogen and the Spatial Structure of the Diffuse X-ray Background.
