Biography
Qijun Wang is a Ph.D. student in the Intelligent Networking and Sensing Systems Lab at MSU, working with Dr. Huacheng Zeng.
Research Interests
Qijun's research focuses on building AI-assisted wireless sensing systems that enable passive and battery-free devices to capture rich physical signals beyond traditional communication. His work spans wireless sensing, RF systems, backscatter communication, and artificial intelligence, with applications in voice sensing, localization, tracking, and security.
He has authored multiple first-authored papers in top-tier venues, including IEEE S&P, UbiComp, and IEEE INFOCOM. His recent work, RadKey, IEEE S&P 2026, introduces an LLM-guided RF backscatter system for through-wall keystroke inference, highlighting the potential of wireless systems to sense subtle physical dynamics in challenging environments.
