Our group does computer systems research spanning architecture, software systems, and programming languages. We are currently focused on intermittent computing, efficient edge computing, and developing computer systems for emerging small form-factor satellites.
We release code and documentation on Github.

Defining the Intermittent System Stack
Our work is defining the software and hardware system
stack for intermittent computing devices that harvest energy from
their environment. We build real systems for use on Earth and farbeyond.

Efficient Edge Computing
We are developing system software and hardware architectures that make concurrent and parallel computer systems reliable and efficient. We research new parallel computer systems and architectures that make programming easier, that make important applications faster (especially graph computations), and that fill the emerging need for processing at the edge.
