I build systems for estimating nutrient leaching to lakes and sea from land sources on a regional and national scale.


  • Automated creation of risk evaluation maps, for the leaching of nutrients from small suar systems, using high resolution elevation data.
  • Modelling nutrient losses from small agricultural catchments.
  • Further development of a decision support system (FyrisCOST) for cost efficient measures on agriculture land to reduce nutrient leaching.
  • Maintaining and operating modeling framework for MACRO-SE, a national risk assessment tool for pesticide leaching to surface- and ground water.
  • Maintaining, updating and operating the European Integrated Monitoring (IM)-database.


  • Introduction to limnology, in Land use watershed management, MV0217 (earlier MV0194)
  • Models for Water Policy (MX0145)
  • Modelling of nutrient source apportionment at Uppsala University (1TV446)


  • Impact of climate change on water quality and phytoplankton composition in lakes and reservoirs.
  • Modelling of light climate in lakes.


PhD in limnology at Uppsala university 2005. In the period 2006-2009 I spent my postdoc working with water quality scenarios for NYC water supply.

Tools I work a lot with:

  • Python
  • R
  • ArcGIS, QGIS
