Alzheimer’s disease (AD) is the most common cause of dementia and one of the main health problems in the elderly worldwide. The estimated worldwide cost of caring for 47M affected by dementia was US$818 billion in 2015 and UK is expected to have 1M cases by 2021 [1]. Mild cognitive impairment (MCI) is usually considered as an intermediate stage between the cognitive declines associated with normal aging and a state of dementia [2]. To address the challenge of AD, several worldwide ageing studies (cf. [4]) are being undertaken.
These studies often include multiple brain imaging modalities such as EEG, MEG, PET, and MRI. In particular, MEG is a technique specifically designed to measure dynamic neural activity non-invasively featuring very high time and spatial resolution, and has been increasingly applied in the study of MCI and AD. Recent studies based on MEG have also demonstrated that pharmacological treatment for early AD and MCI can slow the progression of the disease [3]. As part of NI Functional Brain Mapping (FBM) facility, an MEG-based brain connectivity study is underway with the objective of characterizing MCI, which is crucial for early detection of progression from MCI to AD. In addition, our recent EU funded project on redesigning dementia care pathway will involve large heterogeneous data.
Working along with these major funded projects, this project will involve performing comprehensive data analysis on multi-modality neuroimaging data to discover stratified neuromarkers for early prediction of an individual’s possible progression to AD.
The PhD researcher will first undertake a thorough review of the AD literature, particularly related with structural and functional connectivity changes in cognitively impaired brain. Next the student will seek to gain access to available multi-modal neuroimaging data and undertake appropriate pre-processing and analysis of the data to attain a deeper insight. This will be followed by a detailed investigation into a range of feature extraction and selection procedures, and machine learning algorithms, so as to identify robust changes in brain patterns related with neuronal connectivity and/or oscillations in the brains of a large population of healthy persons, people with MCI, and AD patients.
Anticipated Outcomes: The neuromarkers identified in the project will have strong potential for inclusion in a clinical procedure that enables clinicians to routinely use MEG and other neuroimaging data in the assessment of individuals presenting with symptoms consistent with early stages of dementia type impairments.

Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.
We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.
In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.
If the University receives a large number of applicants for the project, the following desirable criteria may be applied to shortlist applicants for interview.
The University is an equal opportunities employer and welcomes applicants from all sections of the community, particularly from those with disabilities.
Appointment will be made on merit.
The University offers the following levels of support:
The following scholarship options are available to applicants worldwide:
These scholarships will cover full-time PhD tuition fees for three years (subject to satisfactory academic performance) and will provide a £900 per annum research training support grant (RTSG) to help support the PhD researcher.
Applicants who already hold a doctoral degree or who have been registered on a programme of research leading to the award of a doctoral degree on a full-time basis for more than one year (or part-time equivalent) are NOT eligible to apply for an award.
Please note: you will automatically be entered into the competition for the Full Award, unless you state otherwise in your application.
The scholarship will cover tuition fees at the Home rate and a maintenance allowance of £19,237 (tbc) per annum for three years (subject to satisfactory academic performance).
This scholarship also comes with £900 per annum for three years as a research training support grant (RTSG) allocation to help support the PhD researcher.
Due consideration should be given to financing your studies. Further information on cost of living
