I am a third-year PhD student interested in geometry and complex dynamics, and in particular Hurwitz spaces, Thurston maps and tropical geometry. My supervisor is Rohini Ramadas. I am an organiser for the Dynamics and Group Geometry Early Researchers (DAGGER) seminar at Warwick.

Background

I did my undergraduate degree at Trinity College Dublin from 2017-21, with a year abroad at UCLA, and afterwards studied on the Part III Master's programme at the University of Cambridge.
