I am a third 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.

In August 2018 I was a teaching volunteer at SAMI Maths Camp in Kitale, Kenya. Talk to me if you want to know more!


I completed my master degree at the University of Bonn, where I wrote my thesis with Harry Baik on sticky and slippery laminations of the circle. Before that, I did my bachelor degree at the University of Amsterdam. My bachelor project was on the topic of Sullivan's No Wandering Domain theorem, supervised by Han Peters.
