Professor Prashant Mehta works at the intersection of nonlinear dynamical systems and control theory: Topics include analysis of fundamental limitations in control of nonlinear systems, model reduction methods for complex systems, and phase transition and learning in large-scale dynamic games.
His recent research involves analysis of phase transition in non-cooperative dynamic games with a large number of agents. The work aggregates concepts and techniques from nonlinear dynamical systems, game theory, and statistical mechanics to provide new tools for understanding complex interconnected systems. Specifically, a variant of the classical Kuramoto oscillator model is considered in a novel game-theoretic setting for control. It is shown that the synchronization of coupled oscillators can be interpreted as a solution of a non-cooperative dynamic game. The theoretical research is important to several applications in neuroscience, biology, economics, and large-scale engineering systems.
On the technology side, his recent research includes applications to systems biology and integrated energy efficient building systems. Prior to joining Illinois, Professor Mehta worked at the United Technologies Research Center (UTRC) in the area of modeling and control of combustion instabilities in jet engines and afterburners. The state-of-the-art in control of rotating wave combustion instabilities in jet engines and afterburners is based on a “symmetry breaking” solution that Professor Mehta invented together with his colleagues at UTRC.
