An important unsolved problem in psychology and neuroscience is: what determines the cognitive differences between individual people? And relatedly, why do some people develop psychiatric disorders while others don’t? One clue may come from the fact that human brain wiring is partially specified by our genomes. Modern genetics has found that a large fraction of both inter-individual cognitive differences and psychiatric disorder risk is due to inter-individual variations in our DNA: for example autism is believed to be ~80% genetic, while schizophrenia is ~50% genetic [Mitchell 2018].
Understanding how genes affect cognition requires understanding how the genome sets the rules for brain wiring during early development, which, in combination with a person’s life experience, results in their particular cognitive profile.
In this project, the PhD student will build and study biologically-plausible deep neural networks as simplified models human brains [Doerig et al 2023]. Standard artificial neural networks will be adapted with biological components such as neuronal cell types, astrocytes, and spiking dynamics. This is an example of the growing field of “NeuroAI”, at the interface between computational neuroscience and artificial intelligence [Zador et al 2023].
The project will have three phases:
The results of these simulation studies can be used to make predictions for neuroscience experiments, or inspire new principles for designing next-generation AI systems.
The student will be embedded in the CNET team in the Intelligent Systems Research Centre at Ulster University, and will collaborate with Dr Kevin Mitchell at Trinity College Dublin.
The student will acquire skills in:
Please note that a research proposal is NOT required for this project.
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
