My main research interest is in Quantum Field Theory (QFT) in non-trivial external backgrounds, such as QFT on curved space-times or QFT in background gauge fields, but I also worked on Matrix models (together with Harold Steinacker), QFT on non-commutative space-times, effective string theory, gauge theories, and microlocal analysis.

I am coordinator for the international webinar series Analysis, Quantum Fields, and Probability and LQP Colloquium.

I am Erasmus coordinator for physics.
