Research Interests:

Presently my main research topic is Quantum Field Theory on curved spacetimes. I am particularly interested in applications of methods from microlocal and asymptotic analysis and operator theory.

I am also investigating problems in QED in external potentials and in general gauge theories.

In the 2016-17 academic year I am co-organizing the mathematical physics seminar with Evelyne Miot, see the tentative schedule.

In 2016-19 I am principal investigator in the JCJC grant ANR-16-CE40-0012-01 „Horizons".
