About me
I am a Heisenberg fellow and Privatdozent at the University of Hamburg, where I am a member of the research group Mathematical Logic and Interdisciplinary Applications of Logic at the Department of Mathematics.
My fields of research are Mathematical Logic and Set Theory. My research focuses on the theory of large cardinals, infinitary combinatorics, set-theoretic definability and applications of set theory in algebra.
