Vijay is an Assistant Professor in the Cybersecurity Engineering (CYSE) Department in the School of Engineering and Computing at George Mason University (GMU), Virginia, USA since 2021. Prior to joining Mason, he was a Research Assistant Professor in the Bradley Department of ECE at Virginia Tech, Blacksburg, USA and was affiliated with Wireless@Virginia Tech Research Lab since 2019.

My research interests focus on the experimental research and prototyping of next-generation cellular communication systems in the following key research areas.

  • 6G wireless communications and networking
  • Open Radio Access Network (O-RAN) and xApps/rApps
  • O-RAN security, privacy and testing
  • AI/ML for wireless networks
  • Dynamic Spectrum Sharing in Satellite Bands
  • mmWave Networks
  • 5G/NR positioning systems
  • Space/Non-terrestrial networks

My research is supported in part by the National Science Foundation ( NSF ), National Institute of Standards and Technology ( NIST), National Telecommunications and Information Administration ( NTIA), Commonwealth Cyber Initiative ( CCI). I am an Adjunct faculty member of the Bradley Department of Electrical and Computer Engineering at Virginia Tech. I am also a faculty member of Commonwealth Cyber Initiative (CCI), a Virginia state-wide initiative to foster 5G wireless, autonomous systems, data and cybersecurity research.
