My main interest lies in the realm of classical ‘relativistic’ gravity as described by general relativity and its modifications, particularly in its relation to Galilei-relativistic physics in terms of post-Newtonian expansions.
I believe that for a proper understanding of such relations, one needs to work in a well-defined conceptual framework, enabling the use of systematic methods. In particular, one needs a clear geometric setting in which to analyse the problem at hand.
On a more general note, I am interested in conceptual aspects of (Poincaré-)relativistic physics in a wider sense, and of differential-geometric structures in physics.
