Research

I am interested in numerical methods for partial differential equations.
Hyperbolic systems has been a special interest for a long time. Currantly I am working on perfectly matched absorbing layers for wave propagation problems, methods for second order wave equations, and models for the flow in a network of channels based on the shallow water equation.
Navier-Stokes equations is another interest. Currently my work is directed towards numerical simulation of multiphase flow.
The Schrödinger Equation is a also important for me. In the group working on numerical methods for Quantum Dynamics I focus on high order approximations and accurate numerical boundary closures.
