I am an associated professor at the Math Department of the University of Pisa.
research field is mathematical logic and its applications. The main topics of my research are nonstandard methods and
their foundations, infinite combinatorics (ultrafilters) and
foundational theories of counting (numerosities). Over the last years,
my research focused on the use of nonstandard methods and ultrafilters in
combinatorial number theory and Ramsey theory.
I am a member of the editorial board of the "Journal of
Logic and Analysis".
