I am a PhD candidate at the ILLC, University of Amsterdam, under the supervision of Professor Benedikt Löwe. My project is funded by a doctoral scholarship of the Studienstiftung des deutschen Volkes (German Academic Scholarship Foundation). My interests lie in mathematical logic, the foundations of mathematics and their philosophy.

I wrote my master’s thesis “Loyalty and Faithfulness of Model Constructions for Constructive Set Theory” under the supervision of Professor Benedikt Löwe (abstract, pdf). Note that this online version has a mistake in the proof of Theorem 5.8 but the theorem still holds (see corrigendum).

I am co-organising a contributed symposium on the interplay of metaphysical positions in the philosophy of mathematics and mathematical practice “M²SP: Metaphysics Meets Set Theoretic Practice” with Deniz Sarikaya (see M²SP) at SoPhia 2020 in Salzburg.
I co-organised a conference on logic as a subject on the interface of mathematics and philosophy in Göttingen in 2017 (see LMP2017, in German), and the conference “Foundations in Mathematics: Modern Views” at the MCMP in Munich in 2018 (see FMV2018).
I have been a reviewer for the Annals of Pure and Applied Logic and the Journal of Logic, Language and Information.
