Subject: PhD Positions, 2 available, Numerical Analysis

Outstanding applicants are invited to apply for two PhD projects that
I have available at the University of East Anglia. These position
focus mainly on higher order numerical methods for hyperbolic PDEs.
The details are available at:

The first project is on Geometry, Error and Superconvergence in
Visualization. This PhD project will focus on using the mathematics
behind the approximation to create better visualization techniques.
Specifically, the challenges that come with geometry of irregularly
shaped domains as well as provable error characteristics and requires
both analysis and computations. This project is in collaboration with
Mike Kirby (School of Computing and SCI Institute, University of Utah)
and the PhD will have the opportunity to work for extended periods at
the University of Utah (

The second project is on time integration. It will focus on exploiting
superconvergence for improving the time integration techniques for
hyperbolic equations, focusing on discontinuous Galerkin methods,
especially for nonlinear equations. Computationally efficient
time-space pairings will be developed.
