My research mostly concerns partial differential equations, nonlinear analysis, and numerical analysis.
In the last years, most of my effort has been directed toward hyperbolic equations, hyperbolic formulations
of Einstein’s equations (in particular, constraint-preserving boundary conditions for such formulations), and
the analysis of finite element methods.
