The UCLA Center for Engineering Economics, Learning, and Networks will develop a new wave of ideas, technologies, networks, and systems that change the ways in which people (and devices) interact, communicate, collaborate, learn, teach, and discover. The Center brings together an interdisciplinary group of researchers from diverse disciplines -- including computer science, electrical engineering, economics, and mathematics -- with diverse interests spanning microeconomics, machine learning, multi-agent systems, artificial intelligence, optimization, and physical and social networks, all sharing a common passion: developing rigorous theoretical foundations to shape the design of future generations of networks and systems for interaction.
