I am working in the fields of
Calculus of Variations and Partial Differental Equations.
I am interested in the so-called Regularity Theory, which is the study of the fine structure of the solutions to variational and PDE problems.
Most of my current research is dedicated to Free Boundary Problems.


Epsilon-regularity for the solutions of a free boundary system.
(with Francesco Paolo Maiale and Giorgio Tortone)

Regularity of the two-phase free boundaries - the extended version of the Oberwolfach report of my talk at the 2020 workshop Calculus of Variations.
