  • [Oct. 21, 2010] I am looking to fill two postdoc positions: one for P2P streaming and DECADE; another one for cloud computing, in particular in the context of our Mosaic project. The current plan is one year, starting immediately, and there is a possibility to extend to two years. If you feel that you have a good macth, please drop me a note.

Research

My general research interests include computer networks, wireless networks, sensor networks, mobile computing, and network security. I lead the Laboratory of Networked Systems (LANS) at Yale University.

Currently, my primary research interest is on designing robust, efficient and fair computer networks, where autonomous, heterogeneous traffic controllers optimize their objectives measured by both traditional performance metrics and non-traditional metrics such as economical metrics and survivability.

Research Highlights:

Research Questions and Objectives:

The central question driving much of my research is the following: What are the guiding principles and practical techniques for achieving robust and efficient computer networks?

Our research methodology is to integrate rigorous analysis with careful system design, practical implementation, and whenever possible large-scale field tests with real users.

  • The objective of rigorous analysis is to reveal and derive the most fundamental guiding principles and to provide provable guarantees. As an example, instead of an ad-hoc system design, our P4P framework derives the interfaces between networks and network applications through rigorous primal-dual optimization decomposition. 
  • The objective of system implementation and large-scale field tests is to ground the principles in the real world. Some of our systems have undergone extremely large-scale field tests (e.g., P4P has been test-deployed with millions of real users at five of the largest Internet service providers in the world); some of our tools have been used by multiple other groups around the world (e.g., TORTE and Network Localization).

Students
This is a web page with links to alumni of my group.

I am fortunate to be able to work closely with a stellar group of students. Current students in my group:

There are many more interesting projects than we can actively pursue; thus, I am currently looking for motivated Ph.D. students. One way for checking if you have a reasonable background and if there is a potential match between my research interests and yours, is that you take a look at my current research papers, say those linked at the beginning of this page. If you feel comfortable understanding, and (potentially) criticizing those papers, please feel free to contact with me.

This link contains much useful information for graduate students.

Here is a link to prospective students, current students and prospective visiting researchers.

I used to maintain a list of papers on computer networks. I suggest to my students that they read the papers, at least the red ones.
