Personal details

I hold a BSc and a MSc in computer science from the Department of Mathematics and Computer Science of the University of Udine and was awarded my PhD from the Department of Geography of the University of Zurich in 2013.

I joined the Department of Geography in October 2015 as Lecturer in Quantitative Geography. I'm also Research Associate of the Oxford Internet Institute of the University of Oxford.

Previously, I 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).

I am also:

My research focuses on geographic information science, critical GIS, and quantitative human geography. My 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.

  • 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
