Cyber-physical systems are defined as the joining of and coordination between computational and physical resources. Such systems allow for precise, adaptable, and automatic reactions to real-world stimuli, and therefore offer opportunities for great increases in efficiency and safety in our day-to-day lives. Our group explores the theoretical foundations of CPS design goals, as well as the impact of human dynamics on CPS system implementations.

Built to interact with the physical world, a CPS system must be efficient, reliable, and safe. To optimize such systems, the science of CPS workload characteristics (e.g., self-similarity and non-stationarity) must be established. CPS modeling and design are greatly improved when statistical physics approaches - such as master equations, renormalization group theory, and fractional derivatives - are implemented in the optimization loop.
The networks envisioned within this project consist of tens to hundreds of self-managed, autonomous video nodes scattered throughout an indoor or outdoor environment, capturing, processing, and transmitting relevant video data to other video nodes in the peer-to-peer wireless network. The research problems explored include secure and anonymous wireless routing, distributed power management policies, and resource-constrained video processing techniques.
E-textiles, also called Smart Fabrics, have not only “wearable” capabilities, but also local monitoring, computation, and wireless communication capabilities. Sensors and simple computational elements are embedded into e-textiles, with the goal of gathering sensitive information, monitoring vital statistics and sending them remotely for further processing. Possible applications include medical monitoring, personal information processing systems, or remote monitoring of deployed personnel in military or space applications.
