Broadly speaking, I am interested in the analysis of the regularity properties and the structure and classification of the singularities of solutions to variational problems with an underlying geometric or physical relevance, following an approach which combines state-of-the-art techniques in Geometric Measure Theory, Geometric Analysis, the Calculus of Variations, and PDE. Topics that fascinate me, and on which I have worked or am working include:

  • minimal and almost-minimal surfaces;
  • harmonic maps;
  • branched optimal transport;
  • geometric flows;
  • segregated solutions to systems of PDE.

All my research is available for consultation and download on the arXiv and CVGMT portals
