Postdoc openings - RoboBees Project

Mon, 08/24/2009 - 15:16 — Matt Welsh
The Harvard RoboBees project (http://robobees.seas.harvard.edu) is funded through an NSF Expeditions in Computing grant and is developing an artificial colony of robotic bees. This project involves a wide range of research themes in microscale robotics, multi-agent systems, embedded computing, and novel programming models. The RoboBees project has openings for postdoctoral researchers with expertise in the following areas:
  • Wireless sensor networks
  • Embedded computing
  • Biologically-inspired multiagent systems
  • Swarm robotics
  • Low-power wireless networking
To apply, please send your CV and a brief research statement to Prof. Matt Welsh with the subject line RoboBees Postdoc Application. Before applying for this position, please read over the synopsis of the RoboBees project on our website, and indicate in your application how your research interests overlap with the specific themes above. The application deadline is October 15, 2009. We hope to make decisions by early November.

WhiteFi paper wins Best Paper Award at SIGCOMM 2009

Our paper (joint with Microsoft Research), White Space Networking with Wi-Fi Like Connectivity, won the best paper award at SIGCOMM 2009. More information on the project is in this Technology Review article.

Harvard wins $10M NSF grant

Wed, 08/12/2009 - 18:15 — Matt Welsh
A multidisciplinary team of computer scientists, engineers, and biologists at Harvard received a $10 million National Science Foundation (NSF) Expeditions in Computing grant to fund the development of small-scale mobile robotic devices. The project, entitled RoboBees: A Convergence of Body, Brain, and Colony, will develop an artificial colony of robotic bees, capable of performing tasks such as pollination, search and rescue, and surveillance. HSNL PI Matt Welsh is involved in the project, along with 10 other researchers from Harvard and Northeastern. The project web page is here, and you can read the full press release here.

SHIMMER Technology Exchange

Fri, 08/07/2009 - 11:43 — Matt Welsh
The First SHIMMER Technology Exchange meeting will be held at the Inn at Harvard on October 5-6, 2009. This meeting will provide a forum for the SHIMMER community to learn from one another about important developments and SHIMMER related projects both in the academia and industry. The two day event will include a one day hands-on SHIMMER training course followed by a one day workshop in which researchers will present exciting projects and lead in-depth technical discussions. There will also be an open-mic session where any of the attendees can give a short presentation on what they are doing with SHIMMER. Check out this page for more information about SHIMMER.

IBM Faculty Award

Mon, 08/03/2009 - 09:15 — Matt Welsh
Prof. Matt Welsh has received an IBM Faculty Award for a project entitled "Prototyping the Smart City: Environmental and Energy Monitoring with an Urban-Scale Sensor Network." More details here. We're excited to collaborate with IBM on this effort.

SIGCOMM 2009 paper accepted

Mon, 06/08/2009 - 22:39 — Matt Welsh
HSNL grad student Rohan Murty has a paper coming up in SIGCOMM 2009 on White Space Networking with Wi-Fi like Connectivity. This is joint work with members of Microsoft Research's networking research group, including Ranveer Chandra, Thomas Moscibroda, and Victor (Paramvir) Bahl. The paper describes the first Wi-Fi like wireless network running on top of the UHF "white spaces", portions of the TV band not occupied by TV channels (and other incumbents, such as wireless microphones).

Jim Gray Seed Grant

Thu, 06/04/2009 - 09:25 — Matt Welsh
The HSNL has been awarded a Jim Gray Seed Grant from Microsoft Research for a project called "Rethinking Wireless Networks From the Air Up". This project will explore a new architecture for wireless networks beyond existing standards and protocols, for example, in the UHF white spaces. We will build a software-defined radio testbed at Harvard that will provide full programmability and extensive instrumentation. By permitting reconfiguration at every layer of the protocol stack, we will develop a highly dynamic network architecture that allows for customized policies for managing variable traffic demands.

This project will be headed by HSNL graduate student Rohan Murty and Prof. Matt Welsh. We will collaborate closely with the networking research group at Microsoft Research.
