Research
I work at the dipartimento di ingegneria dell’informazione e scienze matematiche of the University of Siena as a tenure track researcher (rtt).
My research is in descriptive set theory, infinite combinatorics and applications to topology, analysis, model theory, graph theory, computability and theoretical computer science.
For example, I am interested in definable graphs and hypergraphs in descriptive combinatorics, connections with infinite combinatorics such as the Todorcevic’s open colouring axiom, and oligomorphic groups.
I have a scientific habilitation (ASN) for associate professors in Italy and a scientific habilitation in Germany.
I am a board member and Secretary of the European Set Theory Society.
