Postdoc in Oxford with Dyson – Improving Filter Efficiency in Vacuum Cleaners

We invite applications for a Postdoctoral Research Assistant position, jointly funded by Dyson and EPSRC to work with Dr Ian Griffiths and Dr Maria Bruna in the Mathematical Institute.  This is a one-year fixed-term position and is available from 1st November 2016 or as soon as possible thereafter.
Every Dyson vacuum cleaner utilizes a filter to prevent re-emission of dust into the environment. Over time, dust builds up on these filters, resulting in increased energy expenditure on use. Currently, the only way to evaluate filter efficiency is to perform an extensive battery of tests. However, it is difficult to evaluate the cause from the results of these tests due to the large number of variables at play, for example filter porosity, electrostatic charging, and dust particle size distribution. As a result, the task of filter selection and design to extend lifetime is a challenging undertaking.
In this postdoctoral research project we will derive a series of predictive mathematical theories that build upon models that have been developed by our filters research. The successful candidate will get to spend time working in Oxford Mathematics and in the Dyson R&D facilities in Malmesbury, Wiltshire to ensure that our models are tailored to the Dyson product line. In-house experiments will also be conducted to validate our theories at each developmental stage. The resulting models we develop will be used to expedite Dyson’s filter selection and evaluation process, to obtain more energy efficient dust filters in line with future EU regulations.
The successful candidate will have a doctorate in mathematics or a mathematics-related subject.  The candidate should also have knowledge of partial differential equations (PDEs) and scientific computing, in particular for the numerical solution of PDEs and the ability to work independently and to pursue research as part of an interdisciplinary and international team. There is also a requirement to teach some sets of undergraduate or graduate classes, determined by the demand for classes in specific areas.
Applicants should read the job description document before writing their application. You will be required to upload a letter setting out how you meet the selection criteria, a curriculum vitae and the contact details of two referees as part of your online application.  (NOTE: Applicants are responsible for contacting their referees and making sure that their letters are received by the closing date).
Please direct informal enquiries to the Administrative Assistant (email:, quoting vacancy reference 120831.
