I have been involved in the following projects:
Demonstrate, led by Professor Ken Goldberg, placed a camera on Sproul Plaza, the center of Berkeley, and made the camera accessible to the public while also implementing the then-thesis project of Professor Dehzen Song, which explored many users controlling a single device.
TinyOs, led by Professor David Culler, designs the leading operating system that runs on sensor networks.
Harmonia, led by Professor Susan Graham, is an open, extensible framework for constructing interactive, language-aware programming tools.
