Recent Meetings, Interviews, and Presentations
The Partnership for Public Service (PPS) Excellence in Government Fellows (EIG) Program selected GSFC as their lead host for their “2015 Benchmarking Best Practices” session. Each year, the EIG program invites world-class public, private and nonprofit sector leaders to instruct a group of high performing federal employees (GS-14s and 15s) in applying leading management principles to their jobs. “Benchmarking” provides fellows with the opportunity to examine best practices and identify practical, innovative techniques for solving challenges facing government. The on-site session, coordinated by GSFC’s Office of Government & Community Relations, included presentations and follow-on discussions on “Driving Results at NASA Goddard”, led by Deputy Center Director, G Morrow, and NASA Earth Scientist, M Román.
M Román gave an invited talk at the 2015 HyspIRI Product Symposium, June 3 – 5 at GSFC, entitled “CEOS/Land Product Validation Perspective”.
