Charalambou’s research group ICCCSystemS, Information, Communication and Control of Complex Systems is interested in theoretical and technological developments concerning large scale distributed communication and control systems and networks in science and engineering. These include applications in transportation, energy production, distribution, quality, and pricing, water quality and resources, environmental, demographic, agricultural, and societal issues. Current research includes Wireless Communication Systems: modelling and analysis of wireless channels, power control, receiver design, MIMO systems, Information Theory: robust source coding, channel capacity, and quantization, Communication Networks: bandwidth pricing, performance evaluation, QoS, and scheduling, Stochastic Dynamical Systems: stochastic optimization, mini-max games, robust estimation, identification and control, relations between large deviations, robustness, and statistical mechanics, stochastic nano-particle manipulation, Network Control Over Limited Capacity Communication Networks: design of encoders, decoders and controllers to achieve communication and control objectives of embedded systems, centralized and decentralized control and communication of large scale distributed systems.
