Interdisciplinary research at the boundary of Control Systems and Energy Systems with emphasis on Nuclear Fusion and Fission. Control Theory with a focus on Nonlinear Control, Distributed Parameter Systems Control, System Modeling and Identification, Fault Detection. Advanced computational fluid and plasma dynamics. Current efforts focus on the application of advanced control techniques to complex energy systems, such as nuclear fusion reactors (control of plasmas and magnetohydrodynamic flows), coal-based power plants, residential heating/cooling systems and alternative energy systems. Other research interests include control of particle accelerators, control of mechanical systems, autonomous and cooperative control of robots/vehicles, and control of aerospace systems.
