I am a mathematician working in geometric group theory. I like to think about actions on trees and (outer) automorphisms of groups including free groups and free-by-cyclic groups.

I am a postdoc at the University of Oxford, working with Dawid Kielak. From 2017 to 2022 I was a PhD student and then a postdoc at the University of Southampton, working mostly with Armando Martino.

On this site you can see a little more about my research interests, as well as my CV. I am happy to talk about my research – or indeed group theory or maths more generally – in any reasonable context. Feel free to get in touch: you can email me at Naomi [dot] Andrew [at] maths [dot] ox [dot] ac [dot] uk.
