My main expertise is fluvial ecology and ecotoxicology, focused on the ecological effects of chemicals at different levels of biological complexity (from biomarkers to ecosystem processes) and scales of study (in micro- mesocosms and field experiments and watershed-scale biomonitoring). I have investigated the ecotoxicity of metals, pesticides and emerging contaminants in aquatic organisms (biofilms, macroinvertebrates and fish) at the University of Girona in collaboration with several national and international research groups.
