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.
