Two PhD studentships are available with Prof Paul Blackwell, Department of Probability and Statistics, University of Sheffield. Both are fully funded for UK students only, including a full maintenance grant (£13,290 per annum at the 2009/10 rate, increasing for later years). Fees-only studentships may be possible for EU applicants. See the NERC rules (at http://www.nerc.ac.uk/funding/available/postgrad/eligibility.asp) for eligibility details. Applicants should have at least a 2.1 degree in mathematics/statistics. Project 1: uncertainty in marine ecological modelling This project will look at statistical aspects of the modelling of coral and related ecosystems, particularly the handling of uncertainty in modelling and data analysis. The application area presents interesting challenges, since the data available range from high-resolution field data to very large satellite images, and useful models range from the purely statistical to the highly mechanistic. The project will involve collaboration with Professor Peter Mumby, who is currently at Exeter (see http://projects.exeter.ac.uk/msel/) but will be moving shortly to the University of Queensland.

It will involve developing improved methods to extract annual cycles from chemical signals in the ice, which may be noisy or incomplete. The project will be jointly supervised with Dr Nerilie Abram at the BAS in Cambridge. For further details, please see the advert on the BAS site (http://www.antarctica.ac.uk/employment/vacancies/job.php?JobID=527) Applications should be made by 12th March. Please apply online to the University of Sheffield (http://www.shef.ac.uk/postgraduate/online.html) specifying a PhD in Probability and Statistics as the qualification, and Prof. Blackwell as Sheffield supervisor; you do not need to give a detailed project proposal, but should make it clear which project(s) you are interested in. -- Professor P.
