Sam Hughes

Postdoctoral research associate, University of Oxford


I am a postdoctoral research associate in the Mathematical Institute at the University of Oxford working as part of Professor Dawid Kielak's team. Before that (2018-2021), I was a PhD student at the University of Southampton under the supervision of Professor Ian Leary. Even before that (2014-2018), I completed an MMath degree at the University of South Wales.


My research is primarily in geometric group theory, often with a topological flavour. More specifically, I am interested in lattices in locally compact groups, quasi-isometries of pairs, and group cohomology. The latter in relation to finiteness properties, \(\ell^2\)-invariants, and the isomorphism conjectures in \(K\)-theory.


Whilst at Southampton I was one of the organisers of the interdisciplinary seminar series Maths and Mingle. You can read more about Maths and Mingle in our article in the May 2020 edition of the LMS newsletter. I also co-organised the conference Postgraduate Group Theory 2020 (PGTC 2020).
