I am an assistant professor in the Department of Computer Sciences at the University of Wisconsin - Madison since 2025. I am also affiliated with the Department of Electrical and Computer Engineering.

My research interests broadly lie in wireless systems and cyber-physical systems. I lead the MachW Lab with the agenda to build wireless powered systems that perceive the world and communicate with high fidelity unlocking new application potentials.

  • NeRFs for synthetic radar data
  • upsampling architectures for low-res radars
• New wireless communication paradigms
  • multi-bounce wireless imaging
  • mmWave backscatter networking
  • cost effective LEO ground stations
• Wireless + Robotics
  • morphable surfaces for wireless field programming
  • localization of RF tagged whales
  • single-vantage point long range depth imaging
• Emerging applications of wireless signals
  • tire wear sensing
  • low power object localization
  • fine structural health monitoring
