Max Tegmark is a professor at MIT.

Judge as of 2023-06-23. True: MIT's official faculty directory or physics department pages show Max Tegmark held a professorship at MIT (any professor rank) on that date. Mostly true: he held an MIT faculty post on that date but with a different title (e.g. a non-professorial academic appointment). Mostly false: he had been an MIT professor but was not one on that date (e.g. left or retired earlier). False: he never held a professorship at MIT.

3. E3 Written Statement of Dr. Max Tegmark to the AI Insight Forum - Future of Life Institute Future of Life Institute · 24 October 2023 Own record

   “My name is Max Tegmark, and I am a Professor of Physics at MIT’s Institute for Artificial Intelligence and Fundamental Interactions and the Center for Brains, Minds and Machines.”

An MIT Kavli Institute page lists Max Tegmark as "Professor of Physics, Principal Investigator" (E1), and the same page says he arrived at MIT in September 2004 (E2). The MIT page is undated, but a statement dated October 2023 also describes him as a Professor of Physics at MIT (E3). An undated MIT profile lists him as Professor of Physics [E1], the same page says he arrived at MIT in September 2004 [E2], and an October 2023 statement gives the same title [E3]; this is consistent with his being an MIT professor on 23 June 2023.
