What I Work On
Urban Analytics
Understanding how cities function through mobile phone data, social media, and other digital traces — from crowd size estimation to urban vibrancy to access to greenspace.
Transport & Mobility
Analysing patterns of human movement to understand inequality in access to transport, the affordability of public transit, and how COVID-19 restructured people's mobility.
Data Science for Policy
Bridging cutting-edge research and government decision-making — providing evidence to Parliament and co-designing research with teams at the Department for Transport, ONS, and 10 Downing Street.
AI & Society
Exploring how AI and large-scale data can be used responsibly and equitably, while addressing questions of bias, access, and public trust in data-driven systems.

Current Projects
- Bus transport accessibility across England — Using national bus timetable data (BODS) to map how travel time variability affects access to healthcare and other essential services, with direct relevance to transport equity policy.
- Greenspace and recreational value — Quantifying the recreational and wellbeing value of landscape features across England.
- Urban vibrancy and social sensing — Ongoing work using mobile phone data, app usage data, and online traces to understand how different social groups experience and navigate urban environments.
- Knowledge exchange with RAMM, Exeter — Applying data science to visitor behaviour at the Royal Albert Memorial Museum to better understand and anticipate audience patterns.
- Transport equity and journey costs — Analysing the affordability and cost of public transport journeys.
Prospective PhD Students
I welcome enquiries from prospective PhD students interested in working at the intersection of data science, urban analytics, and social inequality. Current areas of particular interest include public transport accessibility and equity, urban vibrancy and social sensing, human mobility modelling, and AI applications in environmental and social contexts.
Funding opportunities include EPSRC and ESRC Doctoral Training Partnerships (through the University of Exeter), as well as project-specific studentships — see the University’s postgraduate research pages for current opportunities. If you have a strong quantitative background and are motivated by research with real-world policy impact, feel free to get in touch with a brief description of your interests.
