I am interested in continuing in the field of scientific
computing. I have developed considerable experience in
the many areas necessary to produce successful scientific
software products and technical results
(e.g. Project management, software engineering,
crystallography, numerical analysis, image processing).
Ideally I would like to extend the application of these skills and my supervisory skills by coordinating a team of scientific programmers working on an interesting and challenging project.
I provide data reduction, analysis, and display support of
the scientific experiments at a major international science institute.
This has resulted in a comprehensive
data analysis and display program called FIT2D. This is the most used
analysis program at the ESRF and is also used by more than 180
external user groups. Information including full documentation is
available at URL:
http://www.esrf.fr/computing/expg/subgroups/data_analysis/FIT2D
The main use of the program is for area data calibration and correction, integration of 2-D data to 1-D ``'' scans, and model fitting of 1-D and 2-D functions to experimental data. A number of papers have been published describing the algorithms.
I also coordinated a team which has successfully developed area detector calibration experimental techniques. This team developed new techniques and improved existing ones. This also involved developing data acquisition systems for test purposes. This work formed the basis of the data acquisition and calibration for crystallography at the ESRF, and has resulted in a number of published papers.
I coordinate an international group working to standardise area detector data formats within the crystallographic community (``imageCIF'').
Recently I have started to work on the problem of fast reconstruction of 3-dimensional tomography data. This has so far involved adapting standard algorithms to improve efficiency, whilst maintaining data quality, and tailoring for an optimised hardware / software configuration using a high performance modern workstation (Compaq XP1000). This is being exploited, and even faster reconstruction algorithms are now being developed.
Following the Ph.D. I continued to work at Birmingham
to extend further the research and to develop
ideas from the thesis work into a practical data analysis system
for data from an X-ray telescope.
The telescope was launched in 1987 and attached to the
Russian MIR space station.
The telescope is a coded mask imaging system of non-cyclic
design and presents many problems of image reconstruction. The
data analysis system was written in FORTRAN 77 on a VAX-11/750
running under the VMS operating system. This system was used for
the reconstruction of raw telemetry data from MIR to 2-D images of the
X-ray sky.
My research at Birmingham was concerned with the imaging properties of coded mask telescopes. Such telescopes work by encoding the observed sources as superposed shadows of a mask pattern; this is called a shadowgram. The shadowgram is recorded by a detector and this forms the data. From the data and knowledge of the mask pattern the original source distribution may be reconstructed; this is usually achieved by computer processing using fast transforms. The technique is used for imaging hard X-rays and Gamma-rays, where focusing devices are/(were) not available, and produces better signal to noise ratios than previous techniques.
My work has involved investigation of the imaging properties of different mask patterns under different conditions with the aim of finding the best mask pattern to use for a particular design of telescope. Linked to this problem various methods of reconstruction have been developed and investigated under different conditions. This has involved producing a large Monte Carlo simulation program to simulate the data formed by different designs of telescopes with various imperfections included in the data. Other programs have been produced to reconstruct the data and to analyse the results. The computing has been carried out using the SERC STARLINK computer node at Birmingham, a VAX-11 750, running under the VMS command system and the programs have been written in FORTRAN 77. In the work I collaborated with Dr. T.J. Ponman and a series of papers were published based on the thesis work.
Additionally, I have been involved in the production of a mask for a coded mask telescope experiment. This required liaising with industrial companies, and with a government research establishment, and in the programming of a computer driven photo-plotter to produce the artwork necessary for a complicated mask pattern.
A quarter of the third year was assessed by a two term long project undertaken concurrently with the lecture courses. Assessment was by a written report submitted at the end of the project. My project was a computing project to evaluate a new method of power spectrum analysis. For the project, I learnt Fortran and took an option in digital data processing for background to the subject. The new method was evaluated by comparison with three existing methods using artificially generated signals with known theoretical power spectra. The new method was based on the maximum entropy method of Gull and Daniell and was compared to the maximum entropy method of Burg and to two traditional methods, one using a truncated autocorrelation function and the other by the averaging of short periodograms of the data. The program was written in FORTRAN 66 and was run on the University Honeywell 6080 computer. The project was successfully completed and showed that the new method gave favourable results. Following graduation my supervisor, Dr. Daniell, and I collaborated in writing a paper of the results. (This paper has since been withdrawn from publication as the identification of a mistake in the published Burg algorithm has made much of the paper outdated.)
