About me

I am a research mathematician based in Madrid; currently Profesora Ayudante Doctor (Lecturer / Assistant professor) at Universidad Autónoma de Madrid, and also member of the Instituto de Ciencias MATemáticas (Mathematical Sciences Institute).

My research is mostly in infinite group theory, particularly groups acting on trees or Cantor sets. I am interested in self-similar groups, profinite groups and more general totally disconnected locally compact groups.

Until September 2020, I was Profesora Ayudante Doctor at the Universidad Carlos III de Madrid. Between 2018 and early 2020, I was Postdoctoral Research Associate in the Zero-Dimensional Symmetry Group , led by George Willis, at the University of Newcastle, Australia. From 2016 to 2018, I was Alexander von Humboldt postdoctoral research fellow at the University of Düsseldorf, Germany, hosted by Benjamin Klopsch. Before that, I was Assistante Postdoctorale in Tatiana Nagnibeda's team at the University of Geneva. I completed my DPhil at the University of Oxford in July 2015, under the supervision of John Wilson and supported by Fundación "la Caixa". My undergraduate degree is from the University of St Andrews, Scotland.
