The role

Help build the next generation of epidemic-behaviour models. This is a rare opportunity to join a pioneering, three-year Leverhulme Trust-funded project that reimagines how epidemic models capture real human behaviour, bringing together mathematical epidemiology, agent-based modelling, and contemporary social and health psychology to fundamentally rethink how we predict and respond to disease outbreaks.

The COVID-19 pandemic exposed the limits of epidemic models that treat human behaviour as an afterthought. This project, "Rethinking Epidemic Models: Integrating Human Behaviour and Psychology", moves beyond simplistic rational-choice or imitation-based assumptions to build models grounded in how people make decisions, through their social identities, group norms, and personal risk judgements. The Leverhulme Trust, one of the UK's most prestigious funders of "original and adventurous research", has backed this genuinely interdisciplinary approach, which challenges the boundaries of mathematical epidemiology and social psychology alike.

You will be based at the Network Science Institute part of Northeastern University London, a vibrant, growing centre for network science, sitting within a wider Institute that also has a presence in Boston and Portland, Maine, with regular exchange of ideas.

Why join us:

• Work at the leading edge of a genuinely new field, designing and building an agent-based modelling (ABM) platform that couples disease transmission with psychologically-grounded behavioural rules – work that will directly shape how future pandemics are modelled and managed.
• Join a truly international, multi-institutional, interdisciplinary team: Professor István Kiss and Dr Andreia Sofia Teixeira at the Network Science Institute, NU London, Professor John Drury at the University of Sussex (a participant in the UK Government's SPI-B group during COVID-19), and Dr Marijn Stok at Utrecht University/RIVM (formerly of the Dutch Corona Behaviour Unit).
• Help build genuinely open science: you will develop and prepare for public release an open-source ABM platform, with your code and methods used and cited well beyond the life of the project.
• Publish in leading interdisciplinary journals and present your work both to network science and psychology audiences (e.g. NetSci, the European Health Psychology Society) and to the multi-agent systems and AI community (e.g. AAMAS, IJCAI) — since a well-built ABM platform has real value and visibility in the computer science world too.
• Build connections across network science, epidemiology, and psychology through regular exchanges with colleagues at Sussex and Utrecht.

Duties and Responsibilities:

• Design and develop a comprehensive agent-based modelling (ABM) platform that integrates disease transmission dynamics with psychologically-grounded behavioural rules, incorporating multi-layered decision-making (group membership, information trust, and risk–vulnerability trade-offs).
• Conduct model parametrisation and systematic sensitivity analyses to identify the behavioural-epidemic feedback mechanisms with the greatest impact on epidemic severity.
• Estimate unobservable behavioural parameters using Approximate Bayesian Computation (ABC) and implement time-series cross-validation to test the models’ predictive performance.
• Perform comparative analyses against traditional (behaviour-free) epidemic models, using measures such as AIC, BIC, and prediction accuracy, to quantify the performance gains from incorporating psychological realism.
• Prepare the ABM platform’s code and documentation for open-source public release, ensuring it is modular and adaptable across different disease and behaviour scenarios.
• Work closely with the project’s PhD student, based at the University of Sussex, to integrate psychologically-grounded behavioural modules into the ABM framework as well as with Professor John Drury at the University of Sussex, and Dr Marijn Stok at Utrecht University.
• Contribute to the extraction and integration of behavioural and epidemiological data from international datasets (UK, Netherlands, USA) and historical outbreaks (2009 H1N1, 2003 SARS).
• Lead and co-author peer-reviewed publications and present findings at interdisciplinary conferences and contribute to the project website and to non-specialist dissemination materials.
• Participate in regular project meetings and research visits across NU London, the University of Sussex, and Utrecht University to ensure effective cross-institutional collaboration.

Experience

Proven experience in agent-based modelling (ABM) and/or computational or mathematical modelling of infectious disease spread. Experience translating theoretical or conceptual constructs into computational rules or algorithms.
