Software-defined Wireless Communications
I am a Research Assistant Professor with the Commonwealth Cyber Initiative (CCI), headquartered at Virginia Tech. My main research interests include open radio access networks, radio virtualization, network slicing, and network orchestration. I have been researching these fields since 2017, when I started my Ph.D. in Electronic & Electrical Engineering. My research experience includes developing software-defined radio systems, implementing radio virtualization mechanisms, and bridging SDR with SDN in support of programmable end-to-end communication networks customized to serve different use cases and applications.
Slicing and combining multiple network segments to build fully-customizable, end-to-end network slices
Virtualizing radios to deploy heterogenous wireless networks on a shared physical network infrastructure
O-RAN xApp Development
Creating a xApp development course, heavily focused on hands-on experience and implementation
mmWave Initial Access
Developing a programmable mmWave platform to enable experimentation on the initial access procedure
Assembling a massive scale SDR testbed for experimentation on future wireless networks... one radio at a time.
