Research interests

My general area of research is feedback control systems. My current research interest is at the intersection between Control and Game Theory. I focus on Nash equilibrium seeking for dynamic agents and qualitative behavior of agents evolving under pseudo-gradient dynamics. Recently, I also study complex transportation systems through the lens of congestion games.
