In August 2020, I completed my Ph.D. in the field of Networked Autonomy from the Massachusetts Institute of Technology (MIT). During this time, I worked with Prof. Eytan Modiano and Prof. Sertac Karaman in the Laboratory of Information and Decision Systems (LIDS). I am also the recipient of the ACM MobiHoc 2018 Best Paper Award for my work on optimizing information freshness in wireless networks.
My current research is in the field of robotic perception, neural networks, and networked communicating systems. My recent work also includes designing communication algorithms with provable guarantees on information freshness and developing a new theory of uncertainty variables.

8 July 2019: Presented our works "Age-Delay Tradeoffs in Single Server Systems" and "When a Heavy Tailed Service Minimizes Age of Information" at ISIT 2019. These work show that age and packet delay are very different metrics, and that minimizing one can result in the worst case performance in terms of the other. [Links to the papers: Link1, Link2]
