The GATEWAY seminar is an informal seminar for junior researchers in 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 you think might interest other G&T postgrads as well can be discussed here.

That said, students and postdocs from other areas are encouraged to participate too! If you are a third or fourth year student interested in geometry you are welcome as well!

The talks usually take place Mondays 2pm-3pm.

If you would like to give a talk or suggest a speaker, please contact Marco Barberis or Esmee te Winkel. We have a limited budget to cover expenses for external speakers.
