FairTorrent project

Coding Seminar

Java on Palm OS


Danny Lewin


My research interests include: networking, P2P systems, content delivery, distributed systems, coding theory, and probabilistic analysis.  Where possible, I like to combine both systems and theory in a project, so that the ideas have a strong theoretical basis and can also be evaluated in practice.

My most recent research is on incentives and performance in Peer-to-Peer file-sharing and streaming systems. Check out the FairTorrent project page.

I used to run a coding theory seminar, which focused on the applications of coding theory in networking. The seminar page contains some useful links to research in coding theory.
