Boundary Integral Equation Methods for High Frequency
Scattering Problems
Project Overview
This is a joint project involving the University of Bath and the
University of Reading on the development of robust methods for
high-frequency wave scattering problems. The project is supported by
EPSRC grants EP/F06795X/1 and
EP/F067798/1 (awarded July 2008), which support the employment of two postdoctoral
research officers, the research time of the
investigators:
Ivan Graham
and Valery
Smyshlyaev (at Bath) and
Simon
Chandler-Wilde
and Steve
Langdon (at
Reading ),
and a visitor's programme involving
Professor
V. Dominguez (University of
Navarra),
Professor M. Ganesh (Colorado School of
Mines) and
Professor Ralf Hiptmair
(ETH Zuerich).
The project also involves strong involvement from four external
bodies: BAE Systems, the UK Met Office, the Institute of Cancer
Research UK and Schlumberger, whose representatives will sit on the
Steering Committee for the project.

- We are pleased to announce the award of 5-year EPSRC Career Acceleration Fellowship to Dr Timo Betcke, our postdoc at Reading, with effect from 1 October 2009. Timo will hold this felowship at Reading, carrying out research on an overlapping project on "Next generation finite element methods for wave problems", working with industrial partner Schlumberger Cambridge Research and a range of UK and international researchers, including Ivan Graham at Bath and Ralf Hiptmair at ETH. As part of his award, Timo has funding for a postdoc and PhD students. We look forward to the formation of Timo's new group and the strengthening of our links between Bath and Reading and with Schlumberger Cambridge Research.
- We are very pleased to have appointed two outstanding postdocs to join the project from March 2009. These are Euan Spence, to be based at Bath, who joins us having completed his PhD with Thanasis Fokas at the University of Cambridge, and Timo Betcke, to be based at Reading, who joins us from a postdoc position at Manchester with Nick Higham, having previously completed with PhD with Nick Trefethen at the University of Oxford.
