    Research

    My research is in Game Theory, specializing in dynamic games and network dynamics. Related to my work in network dynamics, I have also contributed to Probability Theory. Typically, I enjoy working on any puzzling problem that I come across, and therefore my contributions are quite diverse. If forced to list my three most significant contributions, they would be as follows:

    1. Employing information-theoretical tools to study repeated games with memory constraints.
    2. A probabilistic concentration result that has been used in many papers in computational game theory.
    3. The study of various opinion dynamics in networks, which have diverse applications in economics.
