2-Year Postdoctoral Research Position in "Mathematical Modelling of Membrane Filtration of Water"

Vacancy Reference: 
Salary Range: 
Starting Salary £28,983-£30,747
Appointment Term: 
2 years

We invite applications for a postdoctoral research position, funded by the King Abdullah University of Science and Technology (KAUST) Global Research Partnership (GRP), to work with Dr Ian Griffiths and Dr Dominic Vella at the Oxford Centre for Collaborative Applied Mathematics (OCCAM), and in collaboration with Dr Gary Amy at KAUST. This position is available from 1 April 2011 or as soon as possible thereafter.

OCCAM has been established with substantial funding from the KAUST GRP. The Centre, which is part of the Mathematical Institute, is allied to a global network of mathematicians. Aiming to meet the ever-increasing global demand for quantitative understanding of complex scientific phenomena, OCCAM has been built on the strength of four pre-existing groups of applied and computational mathematicians working in Oxford: the Oxford Centre for Industrial and Applied Mathematics, the Centre for Mathematical Biology, the Numerical Analysis Group and the Computational Biology Group. It has a symbiotic relationship with other scientific communities which have a need for problem-solving mathematics both within the University of Oxford and beyond. Over the first five years the Centre will employ 40 new staff and students.

Membrane filtration is becoming an increasingly popular method of water filtration. Membrane systems use a combination of size- and charge-exclusion to filter water, and can be operated through either dead-end filtration or cross-flow filtration. Understanding the relative merits of each of these processes is an important practical question in which theoretical modelling plays an important role. As well as the relative efficacy of filtration in each scenario, it is important to consider the time scale over which the pores clog and hence require cleaning. The principal objective of this research project is to produce a hierarchy of mathematical models to describe the membrane-water-filtration process. By validating with experiments, the resulting models will be used to investigate the optimal operating conditions and to suggest design criteria for different practical scenarios. The outcome will be a better physical understanding of membrane filtration and a series of design criteria that may be used to optimize the process.

This research project will involve collaboration with Dr Gary Amy and the Water Desalination and Reuse Research Center, KAUST, Dr Stephen Peppin from OCCAM, University of Oxford, and Professor Howard Stone and the Complex Fluids Group, Princeton. The project will involve the researcher spending one month working at the Water Desalination and Reuse Research Center and two weeks working in the Complex Fluids Group in each year of the position.

Applicants should have a PhD awarded or a Masters degree and PhD submitted at the time of taking up the position, in mathematics or a related discipline, together with experience of mathematical modelling, analytic and practical scientific computation skills, and fluid mechanics.

Further particulars may be obtained from the Administrative Assistant at The Mathematical Institute, 24-29 St Giles, Oxford, OX1 3LB, email vacancies [-at-] maths [dot] ox [dot] ac [dot] uk and at https://www.maths.ox.ac.uk/notices/vacancies. Applications should include a Curriculum Vitae, a covering letter explaining your suitability for the position and how you meet the selection criteria, and the names and contact details of two referees.  Applications must arrive by noon on 12 January 2011. Ensure that you clearly quote the reference BK/10/46. Candidates should ask their referees to send their references directly to the Administrative Assistant, Mathematical Institute so that they arrive before the closing date. It is the responsibility of candidates to ensure that their references arrive by the closing date.  Interviews will be held in the week starting 14 February 2011.
