Research Fellow / Senior Research Fellow | WorldPop Group, University of Southampton, UK 2026 (Salary Up to £58,225)
The University of Southampton is seeking a Research Fellow or Senior Research Fellow to join its world-renowned WorldPop Group in the School of Geography and Environmental Science. The salary ranges from £36,636 to £58,225 per annum depending on experience and whether the appointment is made at Research Fellow or Senior Research Fellow level. The position is based at the Highfield Campus, Southampton, and is open to applications from international researchers, including those from the Global South. The role focuses on developing and implementing methods for improving small-area modelled human population estimates using geospatial data, statistical modelling, and AI. There is no application fee.
If you are a quantitative researcher with a PhD in demography, geography, statistics, data science, epidemiology, or a related field — with experience in geospatial analysis and population modelling — and you want to work at one of the world’s most globally impactful research groups, producing data that informs UN programmes, public health responses, and humanitarian operations across the Global South — the WorldPop Research Fellow position at the University of Southampton is among the most meaningful and well-compensated research roles available in the UK right now.
What Is WorldPop?
WorldPop is an award-winning, multi-disciplinary research group based in the School of Geography and Environmental Science at the University of Southampton. It was founded with a single, consequential purpose: to produce high-resolution, open-access population data for every country in the world — data that governments, international organisations, and researchers need but often cannot produce themselves.
In practice, WorldPop does something that sounds simple but is technically extraordinary: it generates gridded population estimates at resolutions fine enough to show how many people live in a specific square kilometre of rural Nigeria, urban Bangladesh, or conflict-affected Yemen — and it does this using satellite imagery, building footprints, mobile phone data, census records, and machine learning, integrating sources that no single institution has been able to combine at this scale before.
The impact of WorldPop’s data is direct and measurable. Its population datasets are used by:
- UNICEF and WHO for immunisation campaign planning in low-income countries
- National governments for electoral district design, resource allocation, and infrastructure planning
- Humanitarian organisations for emergency response and displacement tracking
- Climate researchers for modelling the vulnerability of populations to climate hazards
- Public health researchers for disease burden estimation and health systems planning
WorldPop data has been used in responses to Ebola outbreaks in West Africa, COVID-19 planning across sub-Saharan Africa and South Asia, and humanitarian operations in Syria, Yemen, and South Sudan. This is not blue-sky research. It produces outputs that affect decisions that affect lives.

What the Role Involves
The successful candidate will work on the development and implementation of methods for improving small-area modelled human population estimates. This is one of the most technically demanding and globally significant challenges in applied demography and geospatial science — and WorldPop is the world’s leading group working on it.
Specific responsibilities include:
Methodological development. Designing and testing new approaches to process and utilise gridded geospatial datasets — including satellite-derived building footprints, land use classifications, infrastructure layers, and social media-derived spatial signals — to construct higher-resolution and more accurate population estimates.
Integration into WorldPop workflows. Translating new methods into operational pipelines that WorldPop uses to generate its flagship national, regional, and global demographic products.
Research leadership. Leading and contributing to the preparation of high-quality academic publications. Senior Research Fellows are expected to lead publications; Research Fellows contribute substantially and develop toward independent research leadership.
Stakeholder engagement. Presenting outputs to government partners, UN agencies, and other stakeholders. WorldPop works directly with national statistical offices, WHO, UNICEF, and the World Bank — the Research Fellow will have opportunities to represent the group in these settings.
Collaboration. Working as part of a multi-disciplinary team of researchers, data scientists, GIS specialists, and field project coordinators. WorldPop is explicitly a team environment — the ability to work collaboratively across disciplines is essential.
Research Methods and Technical Focus
This is a quantitative, methods-focused position. The technical profile the WorldPop Group is looking for includes:
Geospatial analysis. Experience working with large gridded geospatial datasets — raster data, spatial statistics, coordinate reference systems, and tools such as R (including sf, terra, tidyverse), Python (including geopandas, rasterio), or QGIS/ArcGIS.
Statistical and machine learning modelling. Experience building predictive spatial models — Bayesian hierarchical models, spatial regression, random forests, or deep learning approaches applied to spatial data are all relevant depending on the candidate’s background.
Demographic methods. Knowledge of population modelling concepts — cohort-component models, small-area estimation, spatial interpolation of demographic data — is directly relevant. Candidates from demography, epidemiology, or quantitative geography are particularly competitive.
Big data integration. Experience integrating multiple heterogeneous data sources — satellite imagery, administrative records, census microdata, social media data, mobile phone records — into unified analytical frameworks.
AI and machine learning. WorldPop is actively expanding its use of machine learning — particularly computer vision techniques for building footprint extraction and classification from satellite imagery — and candidates with applied ML skills in spatial contexts are especially valued.
Proficiency in Python and/or R is expected. Experience with cloud computing environments (Google Earth Engine, AWS) and version control (Git) is advantageous.
Why This Role Matters for Global South Researchers
There is a deep irony in the global distribution of population data expertise: the countries about which the most urgent and consequential population data is needed — Nigeria, DRC, India, Bangladesh, Ethiopia, Pakistan, Indonesia — are precisely the countries least well-represented in the research groups producing that data.
WorldPop is acutely aware of this problem. The group explicitly states its commitment to diversity and inclusion and specifically encourages applications from candidates belonging to underrepresented groups within academic posts — including people from Black, Asian, and Minority Ethnic communities.
For researchers from the Global South with the quantitative skills this position requires, there is an additional dimension that goes beyond employment: the opportunity to produce population data for your own region and communities, to shape the methods and assumptions embedded in datasets that affect resource allocation and policy decisions across the Global South, and to do so from within one of the world’s leading research groups.
A researcher from Nigeria who joins WorldPop brings not only technical skills but direct knowledge of the spatial and demographic contexts where WorldPop data is most consequentially used. This knowledge is not incidental — it is analytically valuable. It shapes better research questions, more contextually-grounded methods, and more practically relevant outputs.
