About

I am a Senior Research Engineer at Umeå University in the Responsible AI group.

My research areas include logic and proof theory (in particular deep inference). I am interested in the design of formalisms and systems, as well as in applications of logic for intelligent systems.

Previously, I was a postdoc at IRIF (Univ. Paris Diderot).

I obtained a PhD from the University of Bath under the supervision of Alessio Guglielmi. Before that, I did a MASt in Mathematics at the University of Cambridge (part iii of the mathematical tripos), and even before that I studied an undergraduate in Mathematics at the University of Barcelona.
