About me

I am a postdoctoral researcher at the CMM and the University of Chile, working with Maya Stein. Before, I did my PhD degree at the University of Warwick, where I was very fortunate to be advised by Agelos Georgakopoulos.

Most of my work is in topological graph theory. I am especially interested in problems that lie in the boundary of graph theory, group theory, and geometry. I also enjoy topics of a more enumerative nature.

Together with Haritha Cheriyath we organise the postdoctoral seminar of UChile (SIPo).
