My research is focused on the study of (local and nonlocal) variational models that arise in different situations.

In particular, I am interested in problems with a variational nature from Materials Science, Imaging Science and Big Data.

The general goal is to use rigorous mathematical tools to explain how the basic features of a model relate to the experimental observations,
thus helping to understand the phenomenon under investigation and, eventually, validating (or not) the model.
