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 computing, maths, engineering and natural sciences. Each scholarship is fully-funded for three and a half years (UKRI rates) and includes full course fees, an annual stipend (including 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 University is known for its high-impact research, aimed at solving problems across the globe. Interdisciplinarity, experiential learning, and connection to partners beyond academia are at the heart of the Northeastern University ethos. 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.
The Project
How do higher-order interactions (HOIs) shape the dynamics and emergent properties of neural and social systems?
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
This is the central question driving this PhD project, part of the ERC Consolidator Grant “RUNES” (Reconstruction and Unification of Neural and Social Systems). The successful candidate will contribute to advancing our understanding of HOIs, tackling one of the frontiers in complex systems research by bridging the critical gap between theory and data.
The research program will begin with the development of theoretical models that leverage topological and information-theoretic approaches to describe HOIs. These models aim to uncover how interactions beyond simple pairwise relationships drive phenomena such as synergy, redundancy, and collective behavior in complex systems. Building on this foundation, the project will focus on inference and reconstruction methods, utilizing Bayesian and non-parametric methodologies to infer HOIs from incomplete or low-dimensional data. Computational experiments will explore how HOIs influence system dynamics, including synchronization, contagion, and critical transitions, while empirical applications will validate these models against real-world datasets from neuroscience (e.g., fMRI, EEG) and social systems.
This interdisciplinary project integrates theoretical, computational, and empirical approaches to tackle some of the most pressing questions in the study of complex systems. By exploring HOIs, the research promises to advance our understanding of neural and social systems, paving the way for innovations in modeling emergent behaviors and collective dynamics.
The Successful Candidates Will
- MSc (or equivalent) in Mathematics, Physics, Computer Science, or related fields.
- Strong computational and modeling skills.
- Experience in complex systems, network science, or statistical mechanics.
- Proficiency in programming (e.g., Python, Julia, C++, or similar).
- Excellent communication and collaboration skills.
- Have a proven, strong educational background in history or a related subject (see eligibility criteria)
The successful candidate will join the Network Science Institute within the NPLab (led by Prof. G. Petri), and is expected to interact with members of the group, as well as with postdocs, graduate and PhD students, and to work across a range of applications of network and topological data analysis, both within and outside of the lab.

In addition, the successful candidates 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, Northeastern University 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 at the end of February. Candidates are welcome to contact the NU London supervisor with informal enquiries before the application deadline: Giovanni Petri (giovanni.petri@nulondon.ac.uk)
