Research
My main research interests are in set theory. More specifically, I have worked on the model theory of secondorder set theory (set theory with both sets and classes as objects) and on the foundations of and applications of class forcing. More broadly, I am interested in set theory’s connections to other areas of logic and to philosophy of mathematics.
