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 methods for second order wave equations, and models for the flow in a network of channels based on the shallow water equation.
NavierStokes equations is another interest. Currently my work is directed towards numerical simulation of multiphase flow.
Over the last 10 years much work has concerned perfectly matched absorbing layers for wave propagation problems.
The Schrödinger equation also supports waves. In the group working on numerical methods for Quantum Dynamics I have focused on high order approximations and accurate numerical boundary closures.
