I am occasionally asked by new faculty and grad students (at other schools) whether they should get involved with sensor networks. The concern is that the field has "peaked" and there are risks associated with jumping into an area that may have past its prime. I'm not sure I agree… read moreNovember 06 2009
Today's the last day of SenSys 2009. Some pictures from the poster and demo session are up on the CITRIS website.The morning session on time synchronization features one of the award papers -- Low-power clock synchronization using electromagnetic energy radiating from AC power lines. This is a very well-executed paper… read moreNovember 06 2009
Report from Day Two here at SenSys.Last night at the organizing committee dinner I had the pleasure of chatting with Kris Pister, founder of Dust Networks and the originator of the term "smart dust". I got to pick his brains on the state of sensor networks in industry and the… read moreNovember 05 2009
I'm here in Berkeley for SenSys 2009, the premier venue on sensor network systems. There are 21 papers in the conference this year (out of about 120 submissions) and the quality of the papers is very high. The proceedings have been posted online here. I happen to be the program… read moreOctober 14 2009
Final day here at SOSP 2009. Unfortunately my shuttle back to the airport leaves in the middle of the first session, so I am only able to go to the first couple of talks.Last night at the SIGOPS business meeting, Doug Terry gave an overview of SIGOPS' finances; apparently they… read moreOctober 13 2009
It's Day Two here in Big Sky and we have a few fresh inches of snow on the ground. Apparently Mike Freedman hit an elk while driving here from Salt Lake City on Sunday (he is OK, the elk is likely not).Last night at the banquet and awards ceremony, Eric… read moreOctober 12 2009
I'm in Big Sky, Montana for SOSP 2009 -- widely considered the premier conference on systems. The location is stunning although it's bitterly cold here; I was not ready for this kind of weather for a couple more months. This seems to be the biggest SOSP ever with more than… read moreOctober 05 2009
I happen to be the proud father of a three-month old baby boy named Sidney. He is a great little guy but as a first-time parent I have often been frustrated with the lack of a clear, coherent instruction manual for taking care of newborns. One would think that after… read moreSeptember 22 2009
I have wondered for a while whether the computer science community should not place more value on journal articles, rather than conference papers. Journal articles are not just longer versions of conference papers that take much more time to review -- they are meant to represent a capstone on a… read moreSenSys 2009 Registrations now open
September 21 2009
Registration is now open for SenSys 2009, which will be in Berkeley from November 4-6. The early registration deadline is October 12. The conference program is fantastic and we have Bill Weihl from Google lined up to do a keynote. read morePostdoc openings on the RoboBees project
August 24 2009
The Harvard RoboBees project (which I blogged about previously) has postdoc openings in the areas of wireless sensor networks, embedded computing, swarm robotics, and biologically-inspired multiagent systems. Check out the job posting here for more details. read moreWelcome to Stephen Chong and Krzysztof Gajos

Last year was a huge success for faculty hiring at Harvard CS -- we added three new faculty members to our ranks, two of whom are starting this fall. (Yiling Chen started last year -- she works at the intersection of Computer Science and Economics.) Fortunately, we managed to do… read moreWhiteFi: Wi-fi like networking in the UHF White Spaces
August 19 2009
This week our paper, joint with Microsoft Research, on White Space Networking with Wi-Fi Like Connectivity was presented at SIGCOMM 2009, where it actually won the best paper award. This paper lays the foundations for the first Wi-Fi like network operating in the UHF white spaces (that is, the portions… read moreRoboBees - A Convergence of Body, Brain, and Colony
August 13 2009
I'm part of a team that was recently awarded a $10M NSF "Expeditions in Computing" grant for a project to develop an autonomous colony of robotic bees. This is a big effort headed up by Prof. Rob Wood at Harvard and includes a team of 11 researchers in Computer Science,… read moreJuly 26 2009
The Sensys'09 PC meeting was held here at Harvard a couple of Saturdays ago. I meant to post about this earlier, but a little something got in the way.This year we had 119 full paper submissions (down a bit from last year) and accepted 21 papers, for an acceptance ratio… read more
