My research is mainly focused on problems of mathematical and computational physics; an example of this class of problems is the calculation of the normal modes of an arbitrary domain in two dimensions. This calculation may be done analytically within perturbation theory if the domain is a perturbation of a reference domain (rectangle, circle), or it may carried out numerically, in the case of a general domain.

The images on the left display the first few modes of a domain having the shape of a maple leaf; the modes obey Dirichlet boundary conditions at the border. The internal thin red lines are nodal lines, i.e. lines where the eigenfunction vanishes; the black (solid and dashed) lines are level curves.
