· At the beginning of July 2009, I became Editor-in-Chief for the IEEE/ACM Transactions on Networking (ToN). Check ToN’s web page for instructions on how to submit there. If you have suggestions on how we could make the journal better, send email to ton@seas.upenn.edu.

· I gave a keynote entitled “Does the Networked Generation Need a Next Generation Network?” on July 1^st, 2009 as NGI 2009 in Aveiro, Portugal.

Notes to Ph.D. Applicants

Applications can be completed on-line using the ApplyYourself system. The application deadline for Fall 2010 admission is January 2^nd 2010. I will most likely admit at least one more Ph.D. student next Fall. In case you are interested in working with me, make sure you select in your application at least one of the two following areas of interest: “Social and Technological Networks” and “Wired and Wireless Communication Networks”.

The first area deals with topics that naturally arise in a “networked” environment where users, technology, services interact in a complex manner and together influence each others as well as the evolution of the entire networked systems. Some of the “network economics” projects I am currently involved in fall in that area. The second area targets more traditional networking issues such as routing, traffic engineering, network protocols and network usage, with an emphasis on making the various components of this key infrastructure as simple and robust as possible, so as to achieve the goal of an always on Internet.

Support for most of my research projects comes from the National Science Foundation and industrial partners such as Sprint Labs, Nortel Networks, and Siemens (see individual project pages for details).

Multimedia and Networking Lab

My research is carried out under the auspices of the Multimedia and Networking Lab; a multi-disciplinary lab involving several faculty and exploring a variety of topics broadly connected by their dependency on “networks.” These topics span the various protocols layers, from the physical layer to the application layer, and embody the many opportunities and challenges behind realizing and leveraging ubiquitous communication. Projects in the lab also often involve a mixture of analysis and experiments, with experiments taking advantage of the several local and global testbeds available, many of which were built using equipment generously donated by industry partners.
