My research focuses on the extension of the variational multiscale paradigm to non-standard finite element formulations. Our approach has revealed itself to be a general framework for the derivation of discontinuous Galerkin methods. This formalism provides insights on the numerical behavior of these methods, and a handle on the development of suitable subgrid-scale models. Currently, I am directing my attention to the unification of the variational multiscale method and the use of weakly imposed boundary condition via Nitsche’s method.
