What I do

I am a Visiting Assistant Professor at the Department of Mathematics of the University of Denver.


mathematical logic, universal algebra

Professional Biography

I am a researcher in mathematical logic. I come from Italy, where I graduated in mathematics at the University of Siena, and I obtained my PhD at the University of Pisa. My research interests include algebraic logic, fuzzy logic, and approximate reasoning.


  • Ph.D., Mathematical Logic, University of Pisa, 2018
  • MS, Mathematics, University of Siena, 2013
  • BS, Mathematics, University of Siena, 2011


My research mostly deals with the study of the algebraic semantics of substructural logics, with a particular focus on t-norm based fuzzy logics. I am also studying the logico-algebraic foundations for the probability theory of many-valued events.

Areas of Research

algebraic logic
mathematical fuzzy logic
reasoning under uncertainty
