Research Overview
My research is focused on the full stack of a communication network, starting from PHY, MAC, and network layer, with an extensive focus on prototyping and validating the solutions on an experimental testbed. I have used tools from online learning, causal inference, and signal processing for my research.
In the following, I have put an overview of the published projects.
