The electromagnetic (EM) spectrum is a scarce resource, in which a variety of friendly, unfriendly and neutral entities contend for available spectrum at any given time, location and frequency. DoD radio frequency (RF) systems, such as communication networks and radar, must operate within the context of an increasingly congested and contested electromagnetic spectrum.
The majority of work to develop and mature military wireless networks to date has focused on efficiency and stability in benign conditions. Insufficient attention has been paid to identifying and mitigating vulnerabilities arising from the new features being added to make these networks more efficient. Unfortunately, because of the focus on efficiency, the protocols that have been developed implicitly trust all information shared about the state of the nodes and the larger network. Consequently, when the information that is shared among these nodes is bad, the network quickly becomes unusable.
Program Manager
Dr. Jeff Maas joined DARPA in April 2018 as a program manager in the Strategic Technology Office. Dr. Maas' research interests include electronic warfare applications involving distributed systems, real-time effectiveness monitoring, and strategic employment concepts.
Program Manager
Dr. Seth Cohen joined DARPA as a Program Manager in August 2019. He is interested in novel materials, new approaches to therapeutics/countermeasures, and biological and chemical technologies for stabilization/acquisition of scarce resources.
Office Director
Dr. Timothy Grayson is the director of the Strategic Technology Office (STO) at DARPA. In this role, he leads the office in development of breakthrough technologies to enable warfighters to field, operate, and adapt distributed, joint, multi-domain combat capabilities at continuous speed. These technologies include sensing, communications, and electronic warfare technology and the supporting tools and decision aids needed to compose, integrate, and operate complex combat architectures.
