Guillermo Badia

I am a Senior Lecturer in Logic in the School of Historical and Philosophical Inquiry at The University of Queensland, Australia.

I serve on the editorial boards of Archive for Mathematical Logic and Journal of Multiple-Valued Logic and Soft Computing. I am also a member of the Executive of the Australasian Association of Philosophy, and from 2026, I will be Chair of the Committee on Logic in Australasia of the Association for Symbolic Logic.

RESEARCH INTERESTS: Logic in Computer Science. Semiring-based Logics and Models of Computation. Modal, Intuitionistic and other Non-classical Logics.

From 2022-2025, my work was supported by the Discovery Early Career Researcher Award DE220100544 (383,975 AUD in funds) given by the Australian Research Council.

According to the Mathematics Genealogy Project, I am one of the many academic descendants of G. H. Hardy through the path G. H. Hardy - R. Rado - K. Gravett - John N. Crossley - John L. Bell - G. Priest - Z. Weber - me.

Jointly with John N. Crossley and John Stillwell, I have written a book entitled What is Mathematical Logic?, 2ed., to be published by Oxford University Press in 2025. The website of the book to order is here.
