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.
