Research Interests

I'm interested in (1) designing, building, and deploying trillions of tiny energy harvesting computers that run for decades, supporting global scale applications ranging from healthcare to space exploration, wildlife tracking to horticulture. (2) building fully integrated systems that support positive health outcomes through long term monitoring, intervention development, provider care, or human studies support.  

My research investigates how we can make this possible. I explore and develop new hardware designs, software techniques, tools, and programming abstractions so that developers can easily design, debug, and deploy intricate sensing systems (often energy harvesting and battery-free) that work in spite of frequent power failures, constrained resources, and unpredictable unpredictable human or environmental behaviors.
