The scientific aim of this postdoctoral position is to discover the underlying mechanisms that allow fish to see the polarization of light, and to develop a behavioural assay for the robust assessment of polarization vision. You will complete microspectrophotometry studies of rod and cone photoreceptors; testing the hypothesis that axial dichroism exists in typical cell spectral classes. You will also use an LCD based technique in a two-alternative, forced-choice task to test the behavioural ability of fish to see the polarization of light independently of any other visual cues. You will have a PhD in biology or biophysics with expertise in microspectrophotometry of biological cells. Experience in quantitative animal behavioural studies is also essential.

Applications are invited for a twenty-three month postdoctoral research assistantship to work on the EPSRC-funded project, Hypersaline Discharges Into Tidal Coastal Waters, with Dr Andrew Hogg in the Department of Mathematics, University of Bristol. This position is part of a multi-stranded research initiative that features laboratory and field measurements, mathematical modelling and numerical simulation to analyse the fate and dilution of hyper-saline brine discharged into coastal waters. The research is conducted jointly with Prof. Peter Davies (University of Dundee) and Dr Yakun Guo (University of Aberdeen) and there are other postdoctoral researchers associated with this project in each of these institutions.

The Graduate School of Education is seeking a capable, thoughtful and organised person to take on a new Research Assistant role, working on a Leverhulme Trust funded research project entitled 'Investigating and exploring relationships between economic activity and mathematics learning'. The main objective of the project is to study the mathematical thinking involved in children's out-of-school economic activity, and to consider the opportunities for drawing on this activity in the mathematics classroom.
