The Project
The central question of this PhD project is: What are the capabilities of large language models?
Since the advent of the Transformer architecture (Vaswani et al., 2017), large language models (LLMs) have achieved remarkable results - for example, powering generative AI systems such as ChatGPT, which can produce coherent text-based responses to natural language prompts, and supporting improved machine translation processes. But LLMs result from training artificial neural networks using (statistical) machine learning techniques, and like all such systems their operations are opaque. In other words, it is not clear - even to the designers of these systems - how exactly they process inputs to produce outputs, nor (therefore) what exactly their core capabilities are.
Milliere and Buckner (2024) provide a (rare) philosophical introduction to LLMs, pointing to five traditional philosophical issues that arise in relation to them: (1) whether, as sub-symbolic systems, LLMs achieve the compositionality (hence systematicity and productivity) that is widely regarded as characteristic of human thought and language, and which symbolic systems are believed to possess; (2) whether they undermine arguments (e.g. from the poverty of the stimulus) in favour of linguistic nativism, by showing how linguistic capabilities can be learned (by domain general techniques) from available data; (3) whether they can be properly said to understand language, and ground not only linguistic but speaker meaning (i.e., roughly speaking, all three of the traditional components of meaning - sense, reference, and force); (4) to what extent (if any) LLMs contain ‘world models’, or achieve what is elsewhere known as ‘knowledge representation’ concerning non-linguistic matters; and (5) whether LLMs can support cultural learning through linguistic scaffolding.
This PhD project will address two to three of the above issues (depending on the student’s specific interests and expertises), with a view to practical implications e.g. for future (explainable) AI system design, or in the context of the deployment of LLMs and their potential to contribute to problems of bias and/or generate misinformation.
The successful candidate will:
The successful candidate will benefit from a brand new campus on the banks of the River Thames next to Tower Bridge. This is an interdisciplinary, vibrant research environment with international collaboration and networking opportunities and dedicated research space. It will form the hub of a highly experienced, multi-institution supervisory team from NU London and the University of Kent. In addition, successful candidates will benefit from the unique connection to the wider Northeastern University network in North America, providing a range of additional research opportunities and learning resources.
Shortlisted candidates will be interviewed in August 2024. Candidates are welcome to contact the NU London supervisor with informal enquiries before the application deadline: Brian Ball (brian.ball@nulondon.ac.uk).

Northeastern University London
As part of a major investment, Northeastern University London (NU London) has multiple, fully-funded PhD studentships available to accelerate its interdisciplinary research in the humanities, social sciences and digital sciences. Each scholarship is fully-funded for three and a half years (UKRI rates) and includes fees, an annual stipend, an additional London allowance and associated costs, such as training.
NU London is both a UK university governed by UK higher education regulations, and the European campus of Northeastern University – a large, top-tier research intensive, Boston-based institution. Founded in 1898, Northeastern received $230.7m of external research funding in 2022, and is the recognized leader in experience-driven lifelong learning. It has campuses across the United States and Canada (in Boston; Charlotte, North Carolina; Portland, Maine; Oakland, California; San Francisco; Seattle; Silicon Valley; Arlington, Virginia; the Massachusetts communities of Burlington and Nahant; Toronto and Vancouver). Whilst the PhD will be a UK qualification, students will have the opportunity to engage with and visit the Northeastern University network overseas as part of their London-based doctoral studies, providing a truly unique and highly sought-after dimension to their research training.
