About the Project
Supervisory Team: Dr Anna-Stiina Wallinheimo and Prof Ben Waterson
This project explores how artificial intelligence (AI) can enhance decision-making in complex, high-stakes settings while preserving human judgement. Drawing on human factors, cognitive psychology, and human-computer interaction, the research examines trust, transparency, workload, and accountability to inform safer, more explainable, human-centred AI systems.
Across domains such as transport, healthcare, emergency management, defence, and critical infrastructure, human operators often face an overwhelming volume of information and must make rapid, accurate decisions under uncertainty, time pressure, and high cognitive demand, where decision errors can have significant operational, societal, or life-threatening consequences.
While advances in AI, including machine learning and large language models, offer new opportunities to support human decision-making, effectively integrating AI into such complex, high-stakes decision-making environments while preserving human judgement remains a major challenge. This interdisciplinary project will focus on the human aspects of this challenge, investigating how AI system design can best foster collaboration that supports, rather than replaces, the human decision-maker.
Drawing on theories and methods from human factors, cognitive psychology, and human-computer interaction (HCI), the research will investigate the cognitive mechanisms underpinning human-AI collaboration. Research questions are likely to include how AI explanations influence trust and reliance, how system transparency affects operator understanding, and how AI support impacts cognitive workload, situation awareness, decision confidence, and accountability for the human decision-maker.
Ultimately, the aim is to develop evidence-based principles to inform the design of trustworthy and explainable AI systems that enhance human decision-making. The outcomes will support the safe, ethical deployment of AI technologies in high-stakes settings, ensuring intelligent systems remain aligned with human needs, capabilities, and values.
Entry requirements
A UK 2:1 honours degree, or its international equivalent, in one of the following:
- Human Factors
- Psychology
or experience in complex systems.
An understanding of quantitative research methods and the use of experimental designs is essential.
An understanding of and capability in machine learning or large language models is also desirable.
Fees and funding
We offer a range of funding opportunities for both UK and international students. Horizon Europe fee waivers automatically cover the difference between overseas and UK fees for qualifying students.
Competition-based Presidential Bursaries from the University cover the difference between overseas and UK fees for top-ranked applicants.
Competition-based studentships offered by our schools typically cover UK-level tuition fees and a stipend for living costs for top-ranked applicants.
Funding will be awarded on a rolling basis, so apply early for the best opportunity to be considered.
