GTRI is approved for core competencies in seventeen technology areas by OSD/ASDR&E. The core competencies date back to the establishment of the UARC and have been shown, over the history of the GTRI UARC, to link to the vast majority of work currently being performed by GTRI for USG sponsors. For convenience, the core competencies are aggregated into technology groups. Descriptions of these groups are provided in the links below.
