Research
Welcome. I am a Lecturer in Social and Geographic Data Science at the Department of Geography, University College London.
I am mainly interested in urban analytics, geo-demographics, urban transport, spatial inequalities and spatial justice, and big data applications in scarce data environments. I have extensive experience in the domain of Geographic Information Systems, urban studies, and transport research. I also possess a wide skill set in the field of advanced spatial analysis, including experience with Python programming, R scripting, PostgreSQL with PostGIS, and webmapping through Leaflet.js.
Currently I am working on the following projects:
- Re-purposing consumer and administrative data in order to develop robust annual estimates of residential mobility and demographic change in the United Kingdom.
- Exploring the generational and inter-generational movements of family groups across Great Britain.

Projects
Accessibility analysis. Generation of travel time indicators and market access indicators for small administrative units in Ethiopia. This project is part of a wider study conducted by the World Bank that aims to identify and tackle deeply rooted binding constraints that could hamper the gains of economic growth being spread evenly across regions and between rural and urban areas.
Webmapping. Data analysis and visualisations on the geographical distribution of supply and demand for treatment and support for problematic gamblers. The produced maps are available through: www.begambleaware.org/gambleaware-gb-maps.
Website development. GBNames explores the spread of family names across Great Britain, using historic censuses and recent consumer registers, and links surnames to consumer data statistics. The latest version of the website is accessible through: apps.cdrc.ac.uk/gbnames.
Scoping study for the UCL, Bloomsbury and East London Doctoral Training Partnership (UBEL DTP). This scoping report reviews the proposals of the 28 co-funded and collaborative studentships that have been taken on by UBEL DTP between 2018 and 2020 in order to better understand potential factors and themes that underpin successful partnerships and collaborations.
Preparation of selected data products on ethnicity, population churn, migration, and social mobility for the Greater London Authority.
Data analysis using well-known statistical techniques as well as more advanced machine learning classifiers for Harambee Youth Employment Accelerator to better understand, and possibly predict, successful job placements.
