Jonathan is a unix systems administrator for the NASA Center for Climate Simulation at Goddard Space Flight Center. He joined NASA in 2014 to help maintain Goddard's 3.5 petaflop supercomputer, called 'Discover'. He's now working to implement a large-scale OpenStack cluster for data analytics and other tasks performed by the climate science community. Jonathan has worked in HPC since 2011, having built several clusters for the University of North Carolina at Chapel Hill. As part of the National Science Foundation's GENI project, he helped to build over twenty interconnected OpenStack clouds, which combined to function as a testbed for emerging networking technologies, particularly OpenFlow.
