Research Interests:

Most of my research is focused on interactions of microorganisms and pollutants. We are interested in determining the fate of pesticides and other xenobiotics in terrestrial and aquatic environments. We are studying the possible removal of pollutants by influencing their biodegradation or by provoking their complexation to humic material. Other topics of our research are concerned with the use of plant materials for bioremediating contaminated aquatic and terrestrial environments and with the study of the metabolism of imidazolinone herbicides.

Bioremediation research:

  • Microbial transformation of pesticides and other xenobiotics (particularly heterocyclic aromatic compounds, phenols, anilines)
  • Incorporation of pollutants into soil organic matter as a detoxification method
  • Application of enzymes for pollution control
  • Transformation of heterocyclic compounds under anaerobic conditions
  • Use of plant material for decontamination of polluted environments
