Publications

My work develops three connected research lines, each grounded in open and reproducible methods:

  1. Sustainable mobility and Spatial accessibility
  2. Human–environment interactions - How people use and interact with urban and natural environments.
  3. Spatial data science and GeoAI - Open geospatial methods and GeoAI and GenAI approaches for advanced spatial analysis, spatial reasoning, data quality assessment.
