I am currently a postdoc associated to the DNRF Niels Bohr Professorship of
Lars Hesselholt, and part of the
non-commutative geometry group
at the Department of Mathematical Sciences, University of Copenhagen, where I work with
My Erdös number is 11 (using binary notation).
My research is in
set theory; my primary interests are
forcing and descriptive set theory.
At times, the list of papers on my arxiv author's page
may be more up-to-date than the list below.

Recent (and not so recent) talks
Young Set Theory 2016
This year, the famous Young Set Theory Workshop put up its tent in
Copenhagen, organized by Karen Bakke Haga, Vibeke Quorning, Asger
Törnquist, and me. We acknowledge generous support from the DNRF Niels Bohr Professorship of Lars Hesselholt and from the University of Copenhagen.
If you are not a set theorist, maybe you will enjoy these slides;
I made them with a general mathematical audience in mind, for a talk
in the descriptive set theory seminar in Copenhagen on January 9th 2014.
Here are some slides for my talk at the 4th European Set Theory Conference in Barcelona, in July 2013.
