About Ali Enayat

A Spartan version of my CV can be found on a link further down this page, right after "RELATED LINKS".

I began my work as Professor of Logic at the Department of Philosophy, Linguistics and Theory of Science in 2013. Prior to my arrival in Gothenburg, I served as Professor of Mathematics in the Department of Mathematics and Statistics at American University, Washington, DC.

I have also held faculty positions at the Mathematics Departments of Sharif University (Iran), Western Illinois University (USA), and San Jose State University (USA); as well as visiting research positions at IPM (Iran), the Department of Philosophy at Utrecht University (the Netherlands), and the Mittag-Leffler Institute (Sweden).

I grew up in Tehran, Iran during the ancien régime, and graduated from Alborz High School in 1976, three years before the Iranian Revolution, then I went to USA and received my B.S. degree in Mathematics from Iowa State University (1979), and my Ph.D. in Mathematics (1984) from the University of Wisconsin (Madison), under the direction of Ken Kunen with a thesis on models of set theory.


I am a mathematical logician, with a strong interest in the metamathematics of foundational axiomatic systems such as Zermelo-Fraenkel set theory (ZF) and Peano arithmetic (PA). My approach is dominantly model-theoretic and has focused on fragments of ZF, ZF with large cardinals, Quine-Jensen set theory NFU, and arithmetical systems of various flavors, ranging from fragments of PA, all the way to second order arithmetic and its subsystems.

My current research work is focused on model theory of arithmetic and set theory, and axiomatic theories of truth.

Current editorial responsibities:
