Research: I am a third year PhD student supervised by András MáthéLink opens in a new window. My research area is fractal geometry, particularly from the perspective of geometric measure theory & additive combinatorics.

Education: I completed a MSci in Mathematics at the University of Bristol. My fourth year project was supervised by Thomas JordanLink opens in a new window and was entitled 'Large deviations on self-affine sets'.

Preprints: Preprints in preparation.

Administrative duties: I help to organise the DAGGER seminar, an informal seminar for young researchers (Masters, PhD, Postdoc), predominantly in Dynamics. Please email me if you would like to give a talk.
