2006 SIFT "Star Performance" Award. From the company announcement: "In 2006, Robert brought in (or was instrumental in bringing in) four significant programs: COORDINATORS [Phase] 2, Integrated Learning, Deep Green seedling, and SPDR, whose overall value is over $1M -- of which SIFT's share is at least $500K. Plus there is the prospect of substantial future growth and follow on awards ... that could send those totals much higher. .... He has also been instrumental in attracting and retaining several of our recently-hired employees."
