Research interests

I work on mathematical models of communication networks—the title of my research fellowship is Mathematical models of Internet traffic.

My background is in applied probability, and I use probabilistic and statistical tools to investigate problems in queueing theory and network control. I have coauthored a book on large deviations and queues, Big Queues.

I work on applying such tools to problems in communications networks, especially to Internet congestion control, to optical networks, and to switch scheduling.

For more details, see my publications.

Assorted notes

The cost of p2p

Some notes on the cost of streaming and p2p traffic for ISPs. Why is Comcast throttling p2p traffic? Do the issues affect ADSL as well as cable? How much does it actually cost to do p2p?

TCP queueing & congestion control

A bibliography, and my own work.

Statistics

Camden election charts, predictions for the 2006 local election
UK election charts of the 1997 and 2001 elections. These show at a glance which seats are vulnerable, and how big a swing is needed to gain control of parliament.
An interesting way to display sojourns for participants in a workshop
Some R code for biplots [details] and HTML code [demo]
Some R code for searching [search.R], and the accompanying [searchtemplate.html].
