Fixed-term
Salary per annum (£): £39,560 – £43,099
Closing date: 08/11/2026
Overview
As a Research Associate in the GATE (General Architecture for Text Engineering) team, you will conduct cutting-edge research in detecting and analysing online misinformation. Your work will advance explainable methods from machine learning (ML) and natural language processing (NLP) to analyse false and misleading narratives spreading over time and online platforms, working in close collaboration with journalists and fact-checkers. You will also evaluate the accuracy of information provided by widely used chatbots (eg ChatGPT) and AI-generated search overviews. You will follow ethical and legal protocols, ensuring that the AI methods are reliable and robust to adversarial attacks.
Main duties and responsibilities
- Apply natural language processing (NLP) and machine learning techniques to analyse online disinformation narratives in near-real-time social media streams.
- Evaluate the accuracy of online chatbots and AI-generated search overviews.
- Implement explainable, robust, and scalable narrative analysis tools capable of processing large-scale social media streams.
- Set project milestones, test methodologies, maintain documentation, and ensure timely delivery of project deliverables.
- Meet regularly with consortium partners, technical teams, and external stakeholders to align research with practical impact.
- Publish novel techniques and findings in top-tier journals and present at relevant academic, industry, and policy conferences.
- Collaborate effectively with researchers, PhD students, and technical staff across the department and partner organisations.
- Deliver and undertake training in interdisciplinary research skills, including but not limited to NLP, machine learning, social media analysis, web service development and deployment, and computational social sciences.
- Make ethical decisions in research activities – prioritising human rights, freedom of expression, and ethical AI principles – while embedding sustainability into daily work.
