Power Systems

The planning, real-time monitoring and security of future power grids requires modeling and analysis capabilities beyond those available presently. Existing models are becoming obsolete as new technologies such as renewables and power electronic based devices become more prevalent, and traditional power flow simulation algorithms lack the robustness and scalability that is needed to represent combined transmission and distribution systems over all dynamics and contingencies. Our work is based on a unique equivalent split circuit formulation that that enables adaptation and application of techniques that were developed for circuit simulation to robustly analyze power grids. Our software tool, SUGAR, provides a foundation for: i) incorporating transmission and distribution models that capture true physics behavior; ii) unifying steady state, dynamics and transient analyses; iii) assessing feasibility and solution of optimal power flow conditions.

Integrated Circuits

While the end of CMOS scaling is now in sight, the advancement of integrated circuits and systems remains a top priority for the electronics industry. A significant portion of our research has been focused on methodologies that support affordable design in sub-20nm CMOS technologies, but much of that work also includes opportunistic integration of emerging heterogeneous technologies that are compatible with the CMOS. We further explore use of emerging materials and devices (e.g. magnetics, resistance change, phase change, etc.) that provide new computational or storage capabilities when configured in new forms, or applied to specific architectures. Several of our projects target specific system applications in domains such as brain and human interfaces.
