I am a fifth year PhD student at the University of Pennsylvania, Department of Electrical and Systems Engineering, where I am working with Ali Jadbabaie (MIT), George J. Pappas (UPenn).  Here is a link to my Google Scholar profile and ORCID.

  • Research Interests

My research interests lie on the analysis of networked dynamical systems and game theory.  Descriptive keywords: Actuator and Sensor Placement; Kalman filtering; Social Networks, Information Diffusion, Product Adoption; Learning; Differential Privacy.

Tools that I use come from automatic control; game theory; optimization and probability theory; linear algebra.
