Rapid advances in technology now enable simultaneous access to both telephony and Internet services from smart phone devices that people carry with them at all times. Although this convergence of telephony with the Internet offers many benefits, it also provides cyber criminals the ability to develop increasingly sophisticated attacks that combine resources from both the telephony and Internet channels.

The U.S. power grid is being replaced with a smart grid, a complex network of intelligent electronic devices, distributed generators, and dispersed loads, which requires communication networks for management and coordination. Advanced metering infrastructure (AMI) networks are one part of the smart grid to provide two-way communications between smart meters at the consumers' side and the utility companies. AMI networks allow utilities to collect power consumption data at high frequency rates.

The critical role of spectrum as a catalyst for economic growth was highlighted in the 2010 National Broadband Plan (NBP). A challenge for the NBP is realizing optimal spectrum sharing in the presence of interference caused by rogue transmissions from any source, but particularly secondary users who share the spectrum. This complex problem straddles wireless technology, industrial economics, international standards, and regulatory policy.

Increasingly, decisions and actions affecting people's lives are determined by automated systems processing personal data. Excitement about these systems has been accompanied by serious concerns about their opacity and the threats that they pose to privacy, fairness, and other values. Recognizing these concerns, the investigators seek to make real-world automated decision-making systems accountable for privacy and fairness by enabling them to detect and explain violations of these values. The technical work is informed by, and applied to, online advertising, healthcare, an

There are at least two key features of the move to cloud computing that introduce the opportunity for significant leaps forward in computer security for tenant services. First, a compute cloud provides a common software, hardware and management basis for rolling out cross-cutting services en masse that have resisted incremental deployment in a one-service-at-a-time fashion. Second, compute clouds offer providers a broad view of activity across an unprecedented diversity of tenant services.
