My research is on the development of new control theory and mathematical optimization methods for the design of cyber-physical systems, where physical systems affect computations and vice versa in a closed loop - by incorporating computational elements one can design systems with functionalities that are impossible by physical design alone. I am particularly interested in the interplay between the complexity of the algorithms, computing architecture and physical realization, and how these complexities need to be traded off to satisfy given system-wide performance specifications. Central to my work is the use of powerful optimization-based control methods, such as model predictive control (MPC), to handle nonlinearities and uncertainties in a systematic fashion. My particular expertise is in the design of efficient numerical methods and embedded computing architectures for solving advanced optimization, control and estimation problems in real-time. My theoretical research is motivated by and applied to a variety of problems in the design of aerospace, renewable energy and computing systems.
