at least the last 3 years.
Diatoms (microscopic unicellular algae) are excellent indicators
of river water quality, but the difficulty of identification presents
a major obstacle to their use in routine monitoring programmes.
The aim of this project is to apply expert identification systems and
image analysis techniques to develop a computer-aided approach to
diatom identification. Material from a current project in the
Department of Geography on diatoms and river-water quality in NE
England will be used to explore methods of rapid image capture to
develop a reference library of light microscope images of c. 100
taxa, some closely related and morphologically very similar, others
more diverse. This library will then be used to develop methods of
image description and comparison, using easily obtained (though
mathematically complex) morphological and textural attributes.
The successful applicant will be based in the Department of Geography
under the supervision of Dr. S. Juggins but will also spend time
working in the Department of Electrical and Electronic Engineering and
at the Royal Botanic Garden, Edinburgh, under the supervision of
Prof. O. Hinton and Dr. D.G. Mann respectively. The applicant will be
trained in taxonomic methods, diatom systematics, and
statistical/numerical techniques, and will gain experience in
advanced light microscopy, image analysis, and databases.
We are looking for highly motivated applicants with a good honours
degree, normally at least an upper second, with a biological and/or
mathematical/statistical background. Previous experience in one or
more of the following areas would be an advantage: diatom analysis,
image analysis, pattern recognition, neural networks, multivariate
statistics, computer programming.
The student will be appointed from the 1st October 1995 for three
years and will receive the normal NERC maintenance grant of 5260 GB
pounds p.a. plus an additional sum of 1250 GB pounds p.a. as the

Completed application forms should be returned to Dr. S. Juggins
as soon as possible.
