Tuesdays, 2-5pm, 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.
All group members, especially students, are welcome to participate.
These meetings are not open to the public, unless indicated otherwise.
