My research aims to build rigorous foundations and develop new methodologies in optimization and control, game theory, and systems theory for modeling, analysis, design, and control of complex networked systems, in particular communication/computer networks and power networks. A long-term research goal is to create a mathematical underpinning of network architecture that would include a common analytical framework that integrates sensing, computation, communication, control, and incentive, and allow rigorous analysis and systematic design of complex networked systems
