The Network sciEnce, Wireless, and Security laboratory at Virginia Tech (NEWS@VT)  is a research group focused on developing fundamental mathematical tools and principles to design, develop, and build smart, secure, and self-organizing systems, with applications to networks, wireless systems, Internet of things (IoT) systems, smart power grids, and cyber-physical systems. Our research is largely interdisciplinary and draws upon tools from optimization, game theory, machine learning, statistics, control and economics to design and build networks and cyber-physical systems.

We are currently focused on several research thrusts:
  • Machine learning and artificial intelligence (AI) for wireless networks.
  • Distributed and federated machine learning.
  • Wireless cellular and 6G networks.
  • Virtual reality over wireless networks.
  • Large intelligent surfaces and smart environments.
  • Integration of millimeter wave and sub-6 GHz cellular networks.
  • Wireless communications and networking using unmanned aerial vehicles and drones.
  • Autonomous vehicles over wireless networks.
  • The Internet of Things.
  • Age of information.
  • Behavioral game theory.
  • Smart cities and critical infrastructure.
  • Cyber-physical systems.
  • Data analytics.
  • Cybersecurity.
We have an opening for a postdoc in 6G wireless networks, interested candidates should contact Dr. Saad directly.
