I’m a graduate researcher in the University of Washington’s Sensor Systems Laboratory. My latest work focuses on exploring enabling technologies for a battery-free Internet of Things. I co-authored ACM SIGCOMM 2013’s best paper, which introduced Ambient Backscatter, an ultra-low-power passive method for wireless communication. I also currently lead the development team for the WISP, an open-source and hackable battery-free platform which helps researchers rapidly prototype battery-free sensing, computation and communication systems. I’m honored to be a 2015 Google Fellowship recipient in the area of mobile networking.

Research Interests

  • Exploring radio frequency energy harvesting for pervasive computing applications
