My research interests focus on analysis and design of networked systems. I study how limitations on the interactions and information exchanges among subsystems affect the overall performance and behavior of the networked system. A relevant part of my work is at the intersection of control and information theory. I am interest in characterization and design of systems over unreliable communication networks, and to study how control theory can help designing communication systems with access to feedback information. I am also interested in designing distributed networked controllers to improve reliability and performance of networked systems. A related application domain is the development of network distributed agent/systems capable of collectively optimize performances and/or to make complex decisions outside the computing and intelligence capabilities of a single agent. Applications include distributed robust optimization algorithms for learning and decision making, cooperative autonomous multi-agent robotic systems, and control of smart grids.
