I am a researcher and lecturer in mathematical logic. My research interests are in set theory, specifically the
structure of the real line, regularity properties of sets of reals, descriptive set theory and forcing, as well as the generalized real numbers and generalized Baire spaces.
I obtained my
PhD at the
University of Amsterdam in 2012, under the supervision of
Prof. Benedikt Löwe and prof. Jörg Brendle, and my
Habilitation at Hamburg University in 2018.
My current affiliations are:
Prior to that, I was a Marie Sklodowska-Curie research fellow at Hamburg University, and a postdoctoral researcher at the
Kurt Gödel Research Center for
Mathematical Logic at the University of Vienna (2012-2015), headed by
Prof. Sy David Friedman.
My complete CV can be found here.
