<h3>Postgraduate student at the University of Oxford </h3>


<p id="bio">
I am a fourth year DPhil student at the Mathematical Insitute in the University of Oxford, supervised by <a href="https://www.maths.ox.ac.uk/people/panagiotis.papazoglou">Panos Papazoglou</a>. 
</p>

<p id="bio">
I am funded by a scholarship from the
<a href="https://heilbronn.ac.uk/">Heilbronn Institute for Mathematical Research</a>, and also currently hold a Graduate Development 
Scholarship at St Anne's College. 
</p>

<p id="bio">
I previously completed the MFoCS MSc here at Oxford, funded by a grant from <a href="https://www.jamespantyfedwen.cymru/">the James Pantyfedwen Foundation</a>. 
Before this, I was an undergraduate student at the University of Bristol,
where I earned a BSc in Mathematics and Computer Science.
</p>

<p id="bio">
I am broadly interested in geometric group theory, particularly questions relating to splittings, coarse geometry, 
and algorithmic problems.
