We use advanced magnetic resonance approaches to identify and characterise weak molecular interactions. The aim of this project is to combine both Electron Paramagnetic Resonance (EPR) and Nuclear Magnetic Resonance (NMR) spectroscopic techniques to study such interactions. Modern EPR spectroscopy is quickly moving from being a rather niche technique to a key structurual tool by providing accurate distance information in the nanometer range. Since this is outside the range of typical NOE-based NMR experiments, there is an opportunity to utilise these two techniques in combination to provide unique structural information, especially about dynamic macromolecules.
This PhD project will use a specific biomacromolecular machine which is structurally dynamic and where key functional information relies on understanding the distribution of its various conformational states. We aim to develop and this novel methodology and to then apply it to probe the functional dynamics of this machine using a combination of state-of-the-art magnetic resonance (specifically STD-NMR and PELDOR) techniques in different solvent matrices using a range of both endogenous and exogenous spin probes.
You will join the Henry Wellcome Unit for Biological EPR research team, which together with the UEA NMR facility makes up the core of magnetic resonance infrastructure on the Norwich Research Park. You will be trained to become expert in magnetic resonance spectroscopy with skills in data simulation, spin probe chemistry, isotope labelling and biological chemistry.

This PhD project is offered on a self-funding basis. It is open to applicants with funding or those applying to funding sources. Details of tuition fees can be found at http://www.uea.ac.uk/study/postgraduate/research-degrees/fees-and-funding.
A bench fee is also payable on top of the tuition fee to cover specialist equipment or laboratory costs required for the research. The amount charged annually will vary considerably depending on the nature of the project and applicants should contact the primary supervisor for further information about the fee associated with the project.
The project may be filled before the closing date, so early application is encouraged.
