I have been working in the following areas: Real Analysis, Geometric Measure Theory, Partial Differential Equations, Calculus of Variations and its applications to continuum mechanics (capillarity, pattern formation, phase separation, Ginzburg-Landau vortices).

For each paper below, the version stored here is as close as possible to the published one, but may be not exactly the same. In a few cases I also kept versions which are different from the published one, for example because they contain parts that do not appear in the published version.
Most papers are also available in a paper-saving format (two pages per side, suffix "rdc").
