PhD studentship: X-ray microscopy of synaptic dysfunction during neurodegeneration [Closed]

Published: 15 July 2010
School of Biological Sciences

Working at the interface between neuroscience and physics.

Project Description

Novel high-resolution X-ray microscopy techniques are being created in on-going EPSRC projects at the University of Southampton. These hold the promise of allowing us to directly ‘see’ biological structures with nanometre precision, getting down to the size-scales of the molecular complexes whose properties underlie biological functions from mitochondria to man.

We are looking for a talented individual with a good degree in natural sciences (2.1/1st), and with a good grounding in the physical sciences (eg. ‘A’level physics). You need to have a strong interest in how the molecular machinery of a cell self-organises to produce its function, and how disorganisation can lead to neurological disorders.

The project will involve working at the interface between neuroscience and physics, developing and testing the application of these novel X-ray microscopy techniques to studying the physiology and pathology of neuronal signalling. In the project you would learn tissue-culture of wild-type and transgenic mouse neurones, and the use of conventional confocal & EM microscopy. You would adapt tissue preparation to the new systems, make direct comparisons of X-ray microscopy images to conventional systems, and create new understanding of synaptic and neuronal dysfunction through innovative use of the new technologies. The project will be co-supervised by Dr John Chad (Neuroscience) and Dr Bill Brocklesby (Optoelectronics Research Centre).
