Creating revolutionary scientific breakthroughs AFOSR Mission Expand the horizon of scientific knowledge through leadership and management of the Air Force’s basic research program by investing in basic research efforts in relevant scientific areas. Introduction AFOSR Overview Portfolio Overview Management Summary Technical Summary Future Direction/ Ideas Conclusions Creating revolutionary scientific breakthroughs for the Air Force I’d like to start off with an overview of AFOSR itself, followed by an introduction to my portfolio in D&C, and then Fariba will discuss an area highly linked to many large scale problems in dynamics and control, computational mathematics. Central to AFOSR’s strategy is the transfer of the fruits of basic research to industry, the academic community, and to the other technical directorates of AFRL. Check out www.afosr.af.mil
