Talk Abstract: The promise of wireless power transfer is exciting: cable-free operating rooms, battery-less drones, and factories populated by untethered robots. In short, a technological revolution. Some of the fundamental principles of wireless power have been fully elucidated: any system of transmitting/receive antennas is quantitatively described by an impedance matrix, the activity of matching the load impedance to the radiation impedance of the receive antenna is inconsistent with maximizing transfer efficiency, and efficiency-maximizing antenna currents are solutions to a generalized eigenvector/eigenvalue problem. But it is safe to say that our understanding of wireless power is very much incomplete, and there is considerable scope for breakthrough research, for which possible directions include metamaterials, superco

Talk Abstract: For several decades, my collaborators, students, and I have worked on theory for distributed systems in order to understand their capabilities and limitations in a rigorous, mathematical way. This work has produced many different kinds of results, including:
• Abstract models for problems that are solved by distributed systems, and for the algorithms used to solve them
• Rigorous proofs of algorithm correctness and performance properties (also some error discoveries),
• Impossibility results and lower bounds, expressing inherent limitations of distributed systems,
• Some new algorithms, and
• General mathematical foundations for modeling and analyzing distributed systems.
