The explosive growth of global digital connectivity has opened new possibilities for designing and conducting social science research. Once limited by practical constraints to experiments involving just a few dozen participants—often university students or other easily available groups—or to correlational studies of large datasets without any opportunity for determining causation, scientists can now engage thousands of diverse volunteers online and explore an expanded range of important topics and questions.

Westin Arlington Gateway
DARPA's Defense Sciences Office is sponsoring a Proposers Day to provide information to potential proposers on the objectives of an anticipated Broad Agency Announcement (BAA) for the Next Generation Social Science (NGS2) program. The Proposers Day will be held on March 22, 2016 at the Westin Arlington Gateway (801 N. Glebe Road, Arlington, VA 22203). The event will be webcast for those who would like to participate remotely. Advance registration is required both for attending the Proposers Day in person and for viewing the webcast.

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. Reza Ghanadan joined DARPA in 2013 as a program manager in the Defense Sciences Office. He has interests in data analytics, autonomy, machine learning and artificial intelligence in information and cyber-physical systems. At DARPA, he has been investigating the mathematical foundations and applications of these technologies to complex science and engineering problems, ranging from precision genomics and neuroscience, to robotics and human-machine collaboration.
