Lingjia Liu

Lingjia Liu is a Professor and Bradley Senior Faculty Fellow at Virginia Tech's Bradley Department of Electrical and Computer Engineering. Her research focuses on enabling technologies for 5G/6G networks, including massive MIMO systems, dynamic spectrum access, and AI-driven communication networks. She holds a Ph.D. from Texas A&M University (2008).

Research Interests:

• 5G/6G Network Architectures (3D MIMO, cloud-RAN, ultra-low latency)
• AI in Communications (Reservoir Computing, federated learning)
• IoT & Cyber-Physical Systems (energy harvesting, privacy protection)
• Non-Terrestrial Networks (satellite-based connectivity)

Recent work emphasizes generative AI for network simulation, explainable AI in communication systems, and secure dynamic spectrum sharing. Her research spans theoretical foundations (e.g., OTFS modulation analysis) and practical implementations (e.g., FPGA-based reservoir computing).

Awards: Bradley Senior Faculty Fellow (Virginia Tech).

Her contributions bridge communication theory and AI, addressing 6G challenges through innovative algorithmic and architectural solutions. Current projects explore agentic protocol learning, federated multi-agent RL for spectrum access, and resilient ML under adversarial conditions.
