I have moved to Newcastle, Australia!

This website will not be updated and will disappear in early 2019. I am working on a new one. In the meantime, my contact details can be found above. All my papers and preprints are available on the arXiv.

About me

My main research interests lie within the broad realm of geometric group theory. I am mainly interested in infinite groups, and study them via both algebraic methods and by viewing them as geometric objects and exploiting the geometry or topology of the obtained spaces. The phrase that encompasses my interests is subgroup structure, most notably of groups of (rooted) tree automor- phisms and their relatives of dynamical origin, profinite groups, and totally disconnected locally compact groups.

Since October 2018 I am a postdoctoral research associate in the Zero-Dimensional Symmetry group led by George Willis at the University of Newcastle Australia.

Between September 2016 and September 2018 I was an Alexander von Humboldt postdoctoral research fellow in Benjamin Klopsch's team at the University of Düsseldorf. Previously I was assistante postdoctorale in Tatiana Nagnibeda's team at the University of Geneva. I defended my DPhil in June 2015 under the supervision of John Wilson and supported by Fundación "la Caixa".

Invited talks






I ran the Kinderseminar at Oxford for two years (2013--14). The Kinderseminar is a great way for graduate students to get experience in giving seminar or colloquium-style talks, with a friendly audience and invaluable feedback from Peter Neumann.


I organised, with Benjamin Klopsch, a workshop on Trees, dynamics and locally compact groups, which took place in Düsseldorf on 25th--29th June.

During Michaelmas Term 2013, the topic of the Advanced Algebra Class was amenability. I gave four talks and later wrote up the notes for them (comments/corrections welcome).
