About Me

My research interest is the development, analysis and application of high-order methods to problems of industrial interest. I am particularly interested in methods that are able to account for the exact boundary representation given by a CAD model and my main application fields are computational electromagnetics and computational fluid dynamics. I am also interested in the development of mesh generation techniques for advanced discretisation methods.
