Research Interests & Skills

My research has focused on natural resources soil, water and their interactions with biodiversity, ecosystems conservation and agricultural production. I have particular research interests in:

  • Effects of change in land use and climate on carbon sequestration in soils (stabilization mechanisms) and carbon biomass.
  • Effects of soil type and land use in the processes of erosion, sedimentation, and carbon sequestration.
  • Studies on water quality and the relationship to filtration functions by soils.
  • Effects of climate change on ecosystems.
  • Quantification of environmental ecosystems services.
  • Studies of fertilizer use efficiency in different crops through the use of stable and radioactive isotopes.
