Tuesdays, 1-4pm, 741 Blackett (unless indicated otherwise)

These are informal meetings where we will discuss ongoing research projects.
Sometimes we will discuss more broadly topics of interest and meet academic visitors currently at Imperial.
For background reading, only the most relevant or the most recent reference is given; please follow the paper trail from there.
These meetings are not open to the public, unless indicated otherwise.

Autumn 2007
Winter-Spring 2008

Summer 2008

As usual during the summer, there will be many visitors (mostly from the US) and we will try to make progress on many projects simulataneously, but also to show our guests some good times in London. There will also be two undergraduate researchers joining us at Imperial, Alfred Mallet (Cambridge) and Peter Watson (Oxford).
