To develop a new family of stochastic models for the dynamics of gastro-intestinal nematode parasites in farmed ruminants, which allow accurately for the generation of parasite aggregation by spatial variation in transmission and heterogeneity in host immune responses.
The models will be applied - along with analyses of published and novel epidemiological data - to explore: (a) short and long-term temporal dynamics of parasitism; (b) parasite population genetics (in particular, the persistence of rare parasite genotypes); (c) the population dynamics and genetics of parasite resistance against anthelmintic drugs.
Methodology will involve a combination of stochastic modelling, including approximation and simulation, and empirical data analysis to develop models for (a) the dynamics of parasites within hosts and host immunity; (b) comparison of a family of spatial models and non-spatial approximations for the parasite transmission process.
SUITABLE CANDIDATES will possess good mathematical expertise (ideally with experience of stochastic and spatial processes) and strong programming skills. Either a mathematical/physical science or a quantitative biological background would be appropriate. The project provides an ideal opportunity for either physical scientists or biologists to move into the mathematical biology field.
The successful candidate will spend time in both London and Cambridge groups and could be based in either centre.
For further details, contact Bryan Grenfell and Valerie Isham at the above email addresses.

Applications are invited for a 3-year EPSRC funded postdoctoral research assistantship to work with Dr Colin Sparrow (Cambridge, DPMMS) and Dr Jeremy Gunawardena (BRIMS).
The project aims to make progress in understanding the dynamics of maps which are non-expanding in the sup norm. In many application areas, for example discrete event systems (including networks of linked processors), scheduling problems of various kinds, Bellman operators of games or of Markov decision processes, input-output models in mathematical economics, models of nonlinear diffusion, and in the theory of nonnegative matrices, it is natural to consider maps on R^n which are homogeneous and monotonic, and therefore non-expanding in the sup norm. One basic question is to understand how dynamical information (such as the rate at which trajectories go to infinity) can be used to infer the existence of fixed points. More general questions about maps which are non-expanding are also of interest. We also aim to develop an appropriate theory of stability for dynamical behaviours under perturbations relevant to particular applications (for example a change in the architecture of a network).
Applicants should have, or shortly expect to receive, a PhD in a relevant area of mathematics, or in one of the application areas. Preference will be given to candidates with experience of one or more of the following:

DEPARTMENT OF MATHEMATICS
ADVANCES IN THE THEORY AND PRACTICE OF MULTIWAVELETS
An EPSRC-funded research associate position is currently available for work on the above topic for a period of about two years with Professor AT Walden. Applicants should have, or expect soon to have, a PhD in Mathematics or Statistics, and extensive knowledge and experience of wavelets and time series analysis. Good computing skills are also required.
The salary (in British pounds) will be in the RA1A range 15,159 - 17,606 p.a. plus London Allowance of 2,134.
Applications, with a CV, list of publications and names of at least two referees, and a stamped addressed envelope, should be sent by 28th November 1997 to: Professor A T Walden, Mathematics Department, Imperial College, 180 Queen's Gate, London SW7 2BZ; tel 0171-594 8524; fax 0171-594 8517; email: email@example.com. A formal application form is not issued.Further Particulars:
The Department of Mathematics at Imperial College is one of the largest in the UK, with 48 academic staff (including 15 Professors), some 19 Research Associates/Fellows, and a steady flow of international visitors. In addition, the Department is fortunate in having a number of eminent Emeritus Professors and Senior Research Fellows who play a continuing role in the research life of the Department.
The Department acts as a unified whole in most respects, but for organisational convenience is broken into sections with distinctive research directions: Statistics, Applied Mathematics, Numerical Analysis, Mathematical Physics, and Pure Mathematics.
The Statistics Section has 2 Professors, 3 Visiting Professors, 1 Senior Lecturer and 5 Lecturers. Currently there are 13 postgraduate students and 3 postdoctoral staff. Research areas include Bayesian theory and computation, applied probability, time series and spectral analysis, differential geometry, and design of experiments. Significant research funding is contributed by industrial sponsors in such areas as pharmacokinetics and geophysical time series analysis.
Professor A F M Smith is the past President of the Royal Statistical Society, and received the Guy Medal in Silver from the Society. Visiting Professor John Nelder FRS was awarded the Thomas L Saaty Prize (1990) by the American Journal of Mathematical and Management Sciences. Professor Andrew Walden has served as an Associate Editor for the journal Biometrika and Dr. Jon Wakefield is an Associate Editor for Applied Statistics and a member of the Research Section Committee of the Royal Statistical Society. Many invited lectures at international conferences have been given by members of the Section.
The Department has its own library facilities which are excellent by UK standards. Mathematical Reviews and the Citation Index are both available in an electronic form. The Section has its own cluster of SUN workstations with extensive software and high quality graphics and black and white and colour Postscript printers. In total, the Department has fourteen IBM RS 6000s, 20 SUNs, 8 DEC Alphas and the undergraduate teaching laboratories have 34 NAGA 486 DOS5 workstations and 24 RM Pentiums. The Department's Computer Officer provides technical support for computer users and runs a surgery for those with computer problems. The College also has a central advisory service, including a telephone helpline.
A mathematician, physicist or statistician is required to work on the interface between mathematical modelling and experimentation (for model testing and construction). The project will develop and test a protocol for scaling up from individual to population behaviour in spatially extended botanical and animal epidemics using a combination of spatially explicit stochastic models and nonlinear mean field approximations. The post offers the opportunity to collaborate in a strategically important area of mathematical biology, on the link between modelling, ecological experimentation, and data collection and parameter estimation. The project will characterise the sensitivity of spatially explicit models and their equivalent mean field approximations to changes in individual interactions effected by biological treatments (here typified by biological control agents).
The successful candidate will be a key member of a thriving research group working on theoretical and experimental aspects of plant, animal and microbial populations within the Department of Plant Sciences at Cambridge, and will be supervised by Dr C.A. Gilligan, a mathematical biologist, and Dr, A. Kleczkowski, a mathematical modeller. Additional supervision will be provided by a mathematician, Dr G. Gibson (BioSS, Edinburgh), whose participation in the project is funded through additional research funds from the Scottish Office Agriculture Environment and Fisheries Department. Both the Cambridge and Edinburgh groups have strong links with the U.K. and International community of mathematicians and biologists working on dynamical systems, stochastic processes and mathematical biology.
The post would be ideally suited to a talented researcher with experience in stochastic processes, statistical physics, and nonlinear dynamics but individuals with qualifications in other areas of applied mathematics, statistics and modelling are encouraged to discuss the position with the principal investigators. A Ph.D. is required. Some knowledge of the theory of spatially-extended systems and Cellular Automata would be an advantage.
Applications, including a Curriculum Vitae and the names of two referees should be sent to:
Dr C.A. Gilligan, Department of Plant Sciences, University of Cambridge, Downing Street, Cambridge, CB2 3EA, by 20 October 1997 from whom further details may be obtained.
