I am a second year postgraduate student, supervised by Brian Bowditch and Saul Schleimer. My research interests lie in geometric group theory, hyperbolic geometry and low-dimensional topology. Specifically, I am thinking about quasi-isometric rigidity questions for complexes related to the curve complex.

Together with Marco Barberis, I organise the GATEWAY seminar, a seminar for young researchers in geometry and topology in Warwick.
