About

I am Rajat Talak. I am a Postdoctoral Associate at SPARKlab, at MIT. I work with Prof. Luca Carlone.

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.

Research

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.

You may see a complete list of my publications here or on google scholar.
