Research interests
My research pertains to the calculus of variations and to elliptic partial differential equations (PDEs). The common theme of my contributions is geometric measure theory – the natural language for many geometric variational problems. For instance, for generalized submanifolds with mean curvature (and integer multiplicity), I proved the existence of a geodesic distance and a second fundamental form, and laid the foundation to study PDEs thereon (see publications no. 4, 6, and 8).

Note: The last two sentences of Remark 2.7 therein should have referred to integral varifolds, see Remark 7.7 in Publiction no. 6.
Note: Publications no. 1 and 2 precisely contain the results of my PhD thesis at the University of Tübingen (2008).
The author maintains a list of errata which, apart of one remark in Publication no. 1 (see above), are of typographical nature.
