Synapses are the microprocessors of the mind that encode and store memories. In Alzheimer’s disease (AD), synapses are damaged by the constituents of abnormal beta-amyloid plaques that accumulate in the brain. Indeed, the loss of synapses correlates most closely with cognitive decline in people with AD. Currently, no treatments are available to prevent or slow the progression of AD.
Research in the Frank group is aimed at determining the in situ 3D molecular structures associated with AD to understand disease mechanisms and molecular pathways that can lead to the rational design of a mechanism-based therapy. To this end, we have developed methods combining mouse genetics and cryo-electron microscopy (cryoEM).
The methods used will include: i) Electron tomography and computational image processing. ii) experiments with mouse models of Alzheimer’s disease iii) Biochemical and genetic labelling. Applicants from all backgrounds, including physical, chemical and biological sciences, are encouraged to apply. Some experience with programming (e.g. Python, Matlab or similar) will be highly advantageous.
This project will generate information-rich molecular structures of the mammalian brain that are expected to provide new insights into disease mechanisms. Thus, the student undertaking this research will receive an interdisciplinary training at the cutting edge of structural biology, neuroscience, and dementia research.

Benefits of being in the DiMeN DTP:
This project is part of the Discovery Medicine North Doctoral Training Partnership (DiMeN DTP), a diverse community of PhD students across the North of England researching the major health problems facing the world today. Our partner institutions (Universities of Leeds, Liverpool, Newcastle and Sheffield) are internationally recognised as centres of research excellence and can offer you access to state-of the-art facilities to deliver high impact research.
We are very proud of our student-centred ethos and committed to supporting you throughout your PhD. As part of the DTP, we offer bespoke training in key skills sought after in early career researchers, as well as opportunities to broaden your career horizons in a range of non-academic sectors.
Being funded by the MRC means you can access additional funding for research placements, international training opportunities or internships in science policy, science communication and beyond.
