I'm an Associate Professor in the Computer Science and Electrical
Engineering Departments of Stanford University. I research the design
and implementation of software systems where computers touch the
physical world, such as embedded systems, wireless networks, 3D virtual
worlds, and physical simulation.
I adore excellent engineering and have a self-destructive aversion to
I head the Stanford Information Networking
Group (SING), whose members only sometimes put up with me.

TinyOS Programming Manual
I've recently written a short book on programming TinyOS. Unlike the tutorials,
which are a brief introduction to get you started, or TEPs, which describe
parts of TinyOS 2.0, Programming TinyOS digs into nesC and how you can use it to build TinyOS applications.
Except for a few fictional components in the beginning, almost every concept
has a TinyOS 2.0 implementation as an example. A second version of the text,
co-written with David Gay, is available for purchase as of April 2009. We tried to keep the cost
down by making it softcover and having very tiny royalties. Unfortunately,
though, TinyOS programming is not a blockbuster topic, so the book is
a bit pricier than I'd like. Oh well. You can download the
first half of the published version for free. The first half covers the basics: this
version does not include advanced topics like asynchronous code, writing generics, or
the hardware abstraction architecture.
