Physical Flow over Networks: Analysis, Control and Computation
Add to Google Calendar
Network flow provides a compelling framework to model several civil infrastructure systems, including transportation and power. Traditionally, network flow methodologies have focused predominantly on fast computation of performance metrics in static settings, under only flow conservation. Extensions to additional canonical physical constraints and dynamics underlying civil infrastructure systems, and to robustness analysis and control synthesis have been challenging. This is, in part, due to non-convexity, switched dynamics and hybrid state space. We present recent results that overcome these challenges by exploiting structure through the lens of monotonicity, equivalent relaxation, incremental network reduction, and principled abstraction synthesis. Case studies and examples to illustrate the proposed methodologies will also be presented.

Before joining USC, he was a research scientist in the Laboratory for Information and Decision Systems at MIT. He received his PhD in Electrical and Computer Engineering from the University of California at Santa Barbara. His current research interest is in distributed robust and optimal control, dynamical networks, state-dependent queueing systems, and incentive design, with applications in civil infrastructure and autonomous systems. His recognitions include NSF CAREER, an IEEE CSS George S. Axelby Outstanding Paper Award, and AACC Donald P. Eckman Award.
