The DAGGER seminar is an informal seminar for early researchers in Dynamics, Geometry and Topology at Warwick. The aim is to provide an accessible setting where postgraduate students and postdocs can talk about their research or any topic that they have been learning about recently. In other words, any topic that interests you and that might interest other postgrads can be discussed here.

That said, students and postdocs from other areas are encouraged to participate too! Also, if you are a third or fourth year student interested in these areas you are welcome to join!

The talks will take place Mondays 2pm-3pm, (usually) in B3.02.

If you would like to give a talk or suggest a speaker, please contact AndreasLink opens in a new window, DarraghLink opens in a new window, David, Link opens in a new windowor WillLink opens in a new window.
