Research Scientist

As ecosystem modeller at the Lethbridge Research and Development Centre, the work of my team revolves around the further development of AAFC's whole farm model Holos.

Current research and/or projects

  • An ecological approach, based on carbon flows within the model HOLOS, for understanding responses of Canadian farms to prospective management practices and global changes
  • Agri-environmental indicators on farm level - ammonia volatilization

Research and/or project statements

  • Ecosystem modeling in agriculture
  • Climate change
  • Greenhouse gas emissions
  • N cycling
