Research in the systems group covers the fundamental science and technological aspects of a broad range of areas related to complex control, communication, biological, and social systems. Research projects are led by several faculty members in Electrical Engineering, in collaboration with faculty from other SEAS and Yale departments.
Current research directions include biomemetic sensing, data analysis, adaptive, cooperative and distributed control of complex systems, biomedical image processing, control with communication constraints, network information theory, graphical models, biological and social dynamical systems, robust design, optimization, coding, and economics of wireless networks, as well as designing and operating efficient, robust, and fair Internet networks.
