email: pal at cs stanford edu, but I receive more email than I can handle. Please don't be offended if I don't reply.
I'm an Associate Professor in the Computer Science and Electrical
Engineering Departments of Stanford University.
I head the Stanford Information Networking
Group (SING) and hold the Fletcher Jones Faculty Development Chair.
I research operating
systems, network protocols, hardware and software design
for computers that touch the physical world, such as embedded systems, sensor
networks, mobile phones, green computing, wireless networks, 3D virtual
worlds, and physical simulation.
I co-founded Kumu Networks to
commercialize research from SING on full duplex wireless. I'm now back at Stanford full time.
The results of my research are used by thousands of people, run
on hundreds of thousands
of devices, and are the basis for Internet standards I've co-authored
for connecting physical objects to the Internet.
I've authored over 60 peer reviewed papers, several of which have
received best paper or most
influential paper awards. I've been awarded an NSF CAREER Award and a
New Faculty Fellowship.

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. There's a short errata page.
