Master theses
Students interested in my research area (see Research) may compile Master theses under my supervision. A basic prerequiste for this purpose is sound knowledge of real analysis; ideally, such a course (see Real Analysis I+II below) could already be taken during BSc studies. Thereafter, successful participation in a reading course of mine (see, for instance, Topics in Geometric Analysis I+II below) is strongly recommended. Most topics in the reading courses will pertain to basic geometric measure theory; some topics will also pertain to functional analysis, elliptic partial differential equations, and differential geometry.
PhD theses
The following list of courses exemplifies the material an ideal candidate would have mastered:
 Real analysis (General measures, measurable functions, Lebesgue integration, linear functionals on Lebesgue spaces, Riesz's representation theorem),
 basic geometric measure theory (Grassmann algebra, covering theorems, derivatives of measures, Hausdorff measures, area of Lipschitzian maps, rectifiable sets),
 functional analysis (Banach and Hilbert spaces, distributions, and Sobolev functions),
 partial differential equations (linear elliptic partial differential equations: a priori estimates in Hölder and Sobolev spaces), and
 differential geometry (Riemannian manifolds, submanifolds).
Typically however, completing knowledge of the above material and proceeding to more advanced material will constitute the main part of the first year's work of a PhD student. To obtain an impression of the latter, one may have a look at H. Federer's comprehensive treatise "Geometric Measure Theory" and W. Allard's fundamental paper "On the first variation of a varifold".
