Since October 2021, I am a Severo Ochoa postdoc at the Instituto de Ciencias Matemáticas (ICMAT) in Madrid. Before that, I was a postdoc at the ENS de Lyon, under the supervision of Adrien Le Boudec. I completed my PhD at the University of Geneva, under the direction of Tatiana Nagnibeda.

I work mainly in geometric group theory. I am very interested in growth in finitely generated groups, and particularly in groups of intermediate growth. I am also very interested in self-similar groups, groups generated by automata, branch groups and other groups with interesting actions on topological spaces. Particularly, I strive to establish connections between algebraic or geometric properties of these groups and properties of their actions.

Since Spring 2022, I am the co-organizer of the Group Theory Seminar of the ICMAT, along with Leo Margolis.
