Dr Ana Horta

Ana is a spatial scientist with a research background in geostatistics for environmental applications. She has been involved in research projects which use geostatistical modelling to quantify and map environmental data. Besides her research in geostatistics, Ana has provided environmental consultancy services to private and public companies concerning contamination assessments and environmental strategic assessments. Ana's current research interests include geospatial data analysis and integration, environmental modelling and uncertainty assessment.

Research Interests

  • Geospatial data analysis for environmental and health applications including data mining & data integration
  • Geostatistical modelling algorithms and uncertainty assessment
