Research Interests

Laser based studies of new electronic materials.

I have a long-standing interest in using lasers to study new materials. My latest project involves optical studies of new materials that hold great promise for creating new kinds of electronic devices. For example, I am studying a particular type of atom-sized defect in diamond called an "NV center" that is of interest because it is possible to optically monitor and manipulate the quantum state of a single center. This work part of a broader effort supported by the National Science Foundation supported Center for Integrated Quantum Materials. The Center aims to develop applications for set of extraordinary new quantum materials with a goal of enabling atomic-scale electronics and photonics that transform signal processing and computation.

Learning Through Designing

Since 1996 I have collaborated on a series of projects with the Lifelong Kindergarten Group at the MIT Media Lab. We develop new technologies that, in the spirit of the blocks and fingerpaint of kindergarten, expand the range of what people design and create—and what they learn in the process. For example, I helped design a new generation of "programmable bricks" called Crickets that enable kids to build all kinds of robotic inventions.
