Milan Lopuhaä-Zwakenberg

Pronunciation: [ˈmilɑn loʷpuˈɦaʔa ˈzʋakəmbɛrχ]

From June 2021, I will be a postdoc at the FMT group at University of Twente. A link to a new page will appear soon, hopefully.

I am a postdoc at the Security group at the Technische Universiteit Eindhoven. Currently I work on the BRIDGE project under Boris Škorić. Previously I was a PhD student in algebraic geometry in Nijmegen (old site).

Research interests

I also create problems for the Dutch Linguistics Olympiad. Here is a file with all the problems I have created so far (in Dutch).

I have written an article (in Dutch) about Linguistics Olympiad problems for the Nieuw Archief voor Wiskunde.
