News and recent events
- Postdoc positions available:
applications are invited for two postdoctoral research positions (one at the
University of Birmingham and one at the
University of Manchester)
to work on the integrated EPSRC-funded project
"Numerical Analysis of adaptive UQ algorithms for PDEs with random inputs".
The closing date for applications is 12th February 2017.
Candidates are encouraged to apply for both positions.
- PhD opportunity:
Adaptive numerical algorithms for PDE problems with random data.

giving a talk at the Applied and Computational Mathematics Seminar at Cardiff University.
- 9-13 June, 2016:
Norbert Heuer (Pontificia Universidad Católica de Chile, Santiago, Chile) visited us and gave a talk at the
Applied Mathematics Seminar.
- Paper published:
together with David Silvester we have designed and implemented an adaptive algorithm
for efficient solution of elliptic PDEs with random data.
The adaptive refinement process is driven by precise estimates of the energy error reductions
that will occur if different refinement strategies are pursued.
Numerical experiments were performed using
our freely available software S-IFISS.

- 5-8 April, 2016:
attending the SIAM Conference on Uncertainty Quantification
at EPFL in Lausanne, Switzerland and
speaking at the Minisymposium "Error Estimation and Adaptive Methods for Uncertainty Quantification
in Computational Sciences".
Travel support from The Institute of Mathematics and its Applications
(Small Grant Scheme) to attend the conference is gratefully acknowledged.
- Paper published:
together with Serge Nicaise we studied convergence rates of the h-version of the boundary element method (BEM) on graded meshes for the
electric field integral equation on polyhedral surfaces. We have proved that, even though quasi-optimal convergence of the method holds
under a restriction on the strength of mesh grading,
the h-BEM on sufficiently graded meshes still regains an optimal convergence rate.
