My primary research interests are in model theory, a branch of mathematical logic with a broad range of applications. More specifically, I am interested in applications of model theory in number theory, geometry, algebra, and analysis. My current work is mostly about the Zilber-Pink conjecture and the Existential Closedness conjecture. Zilber-Pink is a far-reaching generalisation of some famous Diophantine conjectures (André-Oort, Manin-Mumford, Mordell-Lang) concerned with "special" solutions of polynomial equations. Existential Closedness is about solvability of systems of equations involving addition, multiplication, and certain "classical" functions, e.g. the complex exponential function or the modular j-function.

In the past I did research in universal algebra studying the first and second order properties of De Morgan algebras and De Morgan functions.
