Research Frontiers

Wireless Sensing

Signals that see: health, materials, and environment without cameras or contact. mmWave, acoustic, WiFi, and RFID as high-fidelity sensors.

Wireless Actuation

Signals that act as: robots, reconfigurable antennas, and smart matter controlled by RF. Liquid-metal antennas, metasurfaces, and electronics-free soft robots.

Wireless Intelligence

Signals that think: AI-augmented networks, distributed MIMO, and spectrum-aware systems. From MegaMIMO to LLM-guided FCC compliance.

Wireless Networking

Signals that connect: from battery-free IoT tags to CubeSats in low Earth orbit. Backscatter, LP-WAN, ambient harvesting, and satellite links.
