Justin van Dijk

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.
