About me

Generalities

These days, I go by the name Ben Forrás, with a Germanised pronunciation [bɛn fo'ʁas]. Feel free to call me Ben. My pronouns are he/him/his in English, er/ihm in German. My full legal name is Bence Forrás, the original pronunciation of which is [ˈbɛnt͡sɛ ˈforːaːʃ].

Here is my curriculum vitæ. My ORCID iD is 0009-0009-4151-6824, and here are links to my genealogy and MathSciNet.

Current affiliation

Since October 2023, I have been a postdoc in the group of Andreas Nickel at the Universität der Bundeswehr in München. See this page for more information.

Starting this autumn, I will be a Walter Benjamin Fellow in the group of Antonio Lei at the University of Ottawa, funded by the German Research Foundation (DFG).
