Gianluigi Oliveri obtained a Laurea (BA) in philosophy from the University of Bari (Italy). After that, he received a DPhil in philosophy from the University of Oxford (GB), and a PhD in cognitive science from the University of Messina (Italy).

His research interests range from the philosophy of mathematics, artificial intelligence, and the philosophy of science, to metaphysics and the history of philosophy.

He has held teaching and research posts at the universities of Reading, Leeds, Keele, Oxford and Palermo, and has been Visiting Scholar at the Sydney Centre for the Foundations of Science of the University of Sydney, Australia. He is, currently, Associate Professor of Logic and the Philosophy of Science at the university of Palermo (Italy), Corresponding Member of the Accademia Nazionale di Scienze, Lettere ed Arti di Palermo (National Academy of Sciences, Letters and Arts of Palermo), and Chairman of the Centro Interdipartimentale per leTecnologie della Conoscenza (Interdepartmental Centre for the Technologies of Knowledge) of the university of Palermo.


Claudio Ternullo (PhD Liverpool, 2012), is currently Beatriu de Pinós (Marie-Sklodowska Curie Actions COFUND) Post-Doctoral Fellow at the University of Barcelona. Previously, he has held positions as post-doc at the Kurt Gödel Research Center for Mathematical Logic at the University of Vienna and at the University of Tartu. His research interests lie in logic and the philosophy of mathematics, in particular in the philosophy of set theory. His work focuses on the set-theoretic multiverse, new axioms (and their justification) and mathematical platonism (in particular, Gödel's Platonism).  He has also done work on issues in ancient and medieval philosophy. 


Stefano Boscolo (PhD Palermo, 2016), is an IT Solution Architect at Volkswagen Group. His current areas of expertise are advanced analytics, cloud computing, and machine learning. After
