The Internet of Things (IoT) is expected to connect our physical world with billions of sensors and actuators, transforming the way we live and work, as well as creating enormous business markets. Security and privacy are seen as the most critical challenges to IoT growth in the future.

WiFi is ubiquitous nowadays and is playing an increasingly important role in our everyday lives. Traditionally, WiFi networks are mainly used for data communication. In recent years, WiFi signals have been exploited for many exciting new applications including wireless health, elderly/patient monitoring, indoor navigation, gesture recognition, etc. One key component for the success of these applications is accurate tracking of movements.

The forthcoming decade will witness an explosion of Internet-of-Things (IoT), which incorporates not only the current mobile devices, but also smart everyday objects equipped with computation, communication and sensing capabilities.  IoT will automate human life through a new wave of applications, such as smart buildings, intelligent connected vehicles, 3D user interfaces, and immersive telepresence.  But to reach its tipping point, IoT still needs two critical foundations: (i) wireless network architectures that can scale to billions of devices, with wire-speed connectivity and low power c

Many complex systems involve large-scale interconnection of agents with heterogeneous information who interact strategically. Such systems are prevalent in diverse domains ranging from cyber-physical systems, transportation networks, financial markets, consumer networks, and more broadly, complex social and economic networks. The strategic interactions of the agents affect both the direct and indirect (inferred) flow of information, hence introducing new challenges to modeling, analysis, and control.

Uncertainties can cause significant performance degradations and functional failures in numerous engineering systems. Examples include (but are not limited to) nanoscale devices and systems with fabrication process variations, robot control without full knowledge of design and/or environmental parameters, energy systems with weather-dependent renewable energy sources, and magnetic resonance imaging (MRI) with incomplete and noisy scanning data.

 Wireless electronic devices are everywhere in our daily lives with applications ranging from data communication to energy transfer and biomedical sensing. Power amplifier (PA) interfaces the antenna and governs the energy efficiency of a wireless transceiver. Its linearity is also of paramount importance to ensure the signal fidelity. Moreover, its broadband operation is highly desired for high-speed communication and high-resolution sensing. However, integrating a PA in silicon entails challenges due to the PA’s nature of large-signal and highly dynamic operation.
