Overview of Research Projects

The current research thrusts of my group focus on: 5G/NextG ajar/open architectures of radio access networks, real-time edge platform architectures, air-interface & networking protocol designs, and experiementation (e.g., https://indiana5gzone.com, https://ninetwelveconvergence.us) to provide feasibility and resilience studies for state-of-the-art theoretical advances in wireless communications & networking, core, and edge computing.
