I will be offering a new class winter 2018; Internet-of-things Sensors, Systems, And Applications; a seminar on exciting emerging work in the wireless sensor networks and mobile computing areas.
I'm interested in 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.
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 energy harvesting, batteryless sensing applications that work in spite of frequent power failures, constrained resources, and unpredictable conditions.
I am looking for highly motivated students to join my lab.

Mayfly is a language and runtime for timely execution of sensing tasks on tiny, intermittently-powered, energy harvesting sensing devices. Mayfly is a coordination language and runtime built on top of Embedded-C that combines intermittent execution fragments to form coherent sensing schedules: maintaining forward progress, data consistency, data freshness, and data utility across multiple power failures. Mayfly makes the passing of time explicit, binding data to the time it was gathered, and keeping track of data and time through power failures.
Flicker is a a platform for quickly prototyping batteryless embedded, energy harvesting sensors. Flicker is an extensible, modular, “plug and play” architecture that supports RFID, solar, and kinetic energy harvesting; passive and active wireless communication; and a wide range of sensors through common peripheral and harvester interconnects.
The Amulet Project envisions computational jewelry, in the form of a bracelet or pendant, that provide the properties essential for successful body-area mHealth networks. These devices coordinate the activity of the body-area network and provide a discreet means for communicating with their wearer. Such devices complement the capabilities of a smartphone, bridging the gap between the type of pervasive computing possible with a mobile phone and that enabled by wearable computing.

Ekho is an emulator capable of recording energy harvesting conditions and accurately recreating those conditions in the lab. This makes it possible to conduct realistic and repeatable experiments involving energy harvesting, intermittently powered devices. Ekho is a general-purpose, mobile tool that supports a wide range of harvesting technologies.
