I am Ali Sadegh Daghighi, an Erdos number 3 mathematician. My area of expertise is mathematical logic, especially set theory.

Currently, I am the deputy director of the Institute for Interdisciplinary Research in Fundamental Sciences (IRFS) at Arak University, Iran. Since January 2019, I am also a member of the board of directors of the Iranian Association for Logic  (IAL), the national umbrella organization in charge of coordinating all logic activities at the Iranian universities and research institutes.

In September 2017, I received my Ph.D.  from the Amirkabir University of Technology in Tehran under the supervision of Massoud Pourmahdian. I got my B.Sc. and M.Sc. degrees from Sharif University of Technology and Amirkabir University of Technology in pure mathematics and mathematical logic respectively.

My research in set theory is mainly concentrated on the interactions of large cardinals and forcing, tree property, infinitary combinatorics, and non-well-founded set theory. I am also interested in Shelah’s PCF theory and Woodin’s Ultimate L project.

More information about my research and other academic/personal activities is available on my Facebook page as well as the Publications, Talks, and Positions sections here on this website. You can find an updated version of my CV here.

My Blog posts are mainly about various topics of my interest ranging from mathematics to astronomy, linguistics, history, literature, and arts. Please feel free to reach out to me via the information available on the Contact page and let me know your feedback.
