I am a first year PhD student at the University of Pennsylvania, Department of Electrical and Systems Engineering, under the supervision of Ali Jadbabaie, and George Pappas.
- Research Interests
In a nutshell, my research interests lie on the analysis of networked dynamical systems, e.g., humane social networks, schools of fish, flocks of UAV, etc., from a game-theoretic point of view.
During the last year (2011-2012) my main concentration was on the study of competitive information diffusion over social networks.

A game-theoretic approach for the diffusion of competitive products over social networks: We consider a non-cooperative simultaneous game among firms that promote their product over a network by choosing appropriate seeds. Specifically, we focus on various questions regarding pure strategy Nash equilibria of these games, including their efficiency.
