Research Interests
I was originally trained as a mathematical physicist specializing in general
relativity. Over the years I have developped a broad interest in several
topics in analysis, geometry and mathematical physics, as well as in mathematics education. My current research
interests include but are not confined to the following list:
- Mathematical General Relativity
- semi-Riemannian geometry in low regularity
- singularity theorems and cosmic censorship
- exact solutions: impulsive gravitational waves
- Algebras of Generalized Functions and Applications
- geometric theory of nonlinear generalized functions
- applications in general relativity
- applications in PDE, in particular regularity theory
- structure theory of algebras of generalized functions
- Mathematics education
- professional knowledge of teachers
- beliefs on teaching and learning mathematics
- didactic of analysis
- Nonlinear PDE/Kinetic Theory
- Time frequency analysis/Modulation spaces
Much of my research was carried out in collaboration with the
international research group
DiANA (which is an acronym for "Differential Algebras and Nonlinear Analysis") based at the Universities of
Vienna and
Innsbruck in Austria, the
University of Ghent in Belgium, as well as at the
University of Southampton and the
University of Loughborough in the UK.
