Stefano De SabbataLecturer in Quantitative Geography

Contact Details


Stefano joined the Department of Geography in October 2015 as Lecturer in Quantitative Geography. He is also Research associate of the Oxford Internet Institute of the University of Oxford.

Previously he was a Researcher at the Oxford Internet Institute of the University of Oxford (2013-2015) and Junior Research Fellow at the Wolfson College of the University of Oxford (2014-2015). Stefano was awarded a PhD from the Department of Geography of the University of Zurich in 2013, and a BSc and a MSc in computer science from the Department of Mathematics and Computer Science of the University of Udine.

Stefano's research focuses on geographic information science, critical GIS, and quantitative human geography. His current research focuses on the analysis and critique of the geographies of information, with a particular interest on internet content production and representativeness, as well as location-based services, working on the concept of geographic relevance, and geographic information retrieval. His teaching and research interests also include geocomputation, information visualization, public participation GIS, volunteer geographic information, and uncertainty in GIS, and a critical approach to data science and big data analysis.

Research Areas for PhD Supervision

Information Geographies, Internet Geographies, Critical GIS, Public Participation GIS, Volunteer Geographic Information, Geocomputation, Visual analytics

I am interested in supervising students on the following topics:

  • Quantitative, network analysis, and visual analytics approaches to “nature 2.0” analysis
  • Use of Public Participation GIS methods in grassroots movements
  • Study of information inequalities: urban/rural divides in access, participation, and representation on the internet
  • Geodemographic analysis
  • Regional analysis of Open Data and Volunteer Geographic Information
  • Quantitative, network analysis, and visual analytics approaches to understanding online activism
  • Development and application of Public Participation GIS approaches

Enquiries: If you are interested in studying for a PhD in one of these research areas, please make informal enquiries via pgrgeog@le.ac.uk.
