Postgraduate student at the University of Oxford

I am a third year DPhil student at the Mathematical Insitute in the University of Oxford, supervised by Panos Papazoglou.

I am funded by a scholarship from the Heilbronn Institute for Mathematical Research, and also currently hold a Graduate Development Scholarship at St Anne's College.

I previously completed the MFoCS MSc here at Oxford, funded by a grant from the James Pantyfedwen Foundation. Before this, I was an undergraduate student at the University of Bristol, where I earned a BSc in Mathematics and Computer Science.

I am broadly interested in geometric group theory, particularly questions relating to splittings, coarse geometry, and algorithmic problems.

Find a CV here, and feel free to get in contact for more detail.
