I am a lecturer at the Amsterdam University College and Privatdozent at Hamburg University, in the Mathematical Logic group
headed by Prof. Benedikt Löwe. Prior to that, I was a Marie SklodowskaCurie research fellow in Hamburg and a postdoctoral researcher at the
Kurt Gödel Research Center for
Mathematical Logic at the University of Vienna, under leadership of
Prof. Sy David Friedman.
I obtained my PhD at the
University of Amsterdam in 2012, under the supervision of Benedikt Löwe and Jörg Brendle, and my Habilitation at the University of Hamburg in 2018.
My research interests are in mathematical logic and set theory, specifically the
structure of the real line, descriptive set theory and forcing.
My complete CV can be found here.
