RESEARCH FELLOWS IN COMPUTATIONAL FLUID DYNAMICS/GEOPHYSICS

THE UNIVERSITY OF LEEDS, SCHOOL OF EARTH SCIENCES

Two NERC-funded postdoctoral positions are available immediately.
The duration of the appointments is negotiable but may be up to three years.
Research is in geomagnetism and dynamo theory, and will involve
numerical simulations of the geodynamo. The successful applicant will
join the Leeds geomagnetism group, currently numbering 5 researchers.
Work will be centered on the development of parallel codes to run on
two different computer clusters, one of 16 Dec Alphas operating as a
Beowulf machine, and a second a high performance machine of 256
processors which is due for installation imminently.

Applicants should have a PhD and research experience in
some of the relevant areas of computational fluid dynamics,
scientific programming in a Unix environment, and
message-passing protocols.

Salary will be on the scale for Research Staff Grade 1A,
within the range £17626-19681 according to qualifications and
relevant experience.

Informal enquiries may be made to Professor David Gubbins
by email [log in to unmask] or to Dr. Andrew Jackson
[log in to unmask], tel +44 113 233 5255 (D. Gubbins).
Information on the department can be found at http://earth.leeds.ac.uk.

Application forms and further particulars may be obtained
from Mr B. Moorcroft, School of Earth Sciences, The University of
Leeds, Leeds  LS2 9JT UK, tel +44 113 343 5254,
fax +44 113 343 5259.

Closing date for applications 31 July 2002.

The University of Leeds promotes an Equal Opportunities Policy.

                      Person Specifications

Minimum Requirements
--------------------
The candidate should have strong mathematical skills, demonstrated
either by thesis work or publications.  A high level of competency in
computing should be shown. This should show knowledge of the Unix
operating system, and the Fortran programming language.  Knowledge of
one of the following should be shown:  Compuatational Fluid Dynamics,
Magnetohydrodynamics or Geomagnetism.  The ability to work
independently and develop innovative models and theories is crucial.
The candidate must be confident in presenting results orally or via
posters, and ability to write coherently and disseminate results
through publications is essential.

Ideal Candidate
---------------
The ideal candidate will have a PhD in geophysics or a related
discipline such as physics, maths or computer science and will fulfill
the minimum criteria listed above.  He or she will already have
demonstrated research excellence through publications within the field
of geophysics. He or she will possess excellent knowledge of Unix,
including understanding of X-windows protocols, and has experience of
writing modular code. He or she will also possess a knowledge of the
'C' programming language, as well as Fortran 90, and parallel computing
protocols such as MPI or PVM. Knowledge of sparse matrix techniques
would be an advantage.


                        Job Description

The Geomagnetism Group in the Department of Earth Sciences, Leeds
University is focussed on understanding how the magnetic field of the
Earth is generated and maintained. The source of the field lies in the
fluid core of the earth, but exact details of the generation process
are poorly understood.  Our studies vary from theoretical simulations
of how magnetic fields can be created, by integrating the underlying
physical equations in a spherical geometry, through to a programme
based on both contemporary and historical observations.

The research fellow will work full time on research into the geomagnetic field.
The work will centre around computational studies of rapidly-rotating
convection in a spherical geometry, and kinematic and dynamical dynamos.

A high level of competency in computing should be shown by the
candidate.  He or she should show knowledge of the Unix operating
system, and the Fortran programming language.  Knowledge of one of the
following should also be shown:  Compuatational Fluid Dynamics,
Magnetohydrodynamics or Geomagnetism.

The RF will be under the supervision of Prof. D Gubbins and
Dr Andrew Jackson, but will be ultimately
responsible to the Head of Department. The ability to work independently is essential, but good communication with the rest of the Geomagnetism Group
is essential.

The ability to publish in learned scientific journals is required, and
results will be expected to be disseminated at international
scientific conferences.

The post is funded by the NERC for 3 years. Salary will be commensurate with age
and experience.
