At present my research interests include: (i) Speciation and bioavailability inorganic contaminants, such as mercury, and (nano)particles in aquatic systems; (ii) Molecular ecotoxicology and effect of contaminants and nanoparticles on physiology, metabolome and transcriptome of aquatic microorganisms. Biomarkers; (iii) In-situ determination of the impact of contamination by lab-on-a-chip. Biosensors; (iv) Population and community ecotoxicology and biodiversity in aquatic systems. Bioindicators.
