Research Activities

• Bioremediation strategies based on microbial biodegradation processes for worst-case scenarios (e.g. spill) of soil contamination with chlorinated s-triazine herbicides, or other xenobiotics.
• Bioassays based on the simple eukaryotic models Saccharomyces cerevisiae and Caenorhabditis elegans for the screening and diagnosis of the toxicity of environmental chemicals (and their metabolites), inclusive of predicting biomarkers and mechanisms of toxicity.
