Research Interests

Professor Urbano’s research interests are in regularity theory for nonlinear partial differential equations, in particular of singular or degenerate type, arising from different applications, like phase transitions, flows in porous media or semi-supervised learning. He is also interested in free boundary problems, with a focus on the understanding of the local behaviour of weak solutions and the geometric properties of interfaces.
