Professor of Logic
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. I 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.
