She has carried out research stays at the University of Wales, Heidelberg University, King’s College School of Medicine and Dentistry, the University of California in San Diego and the University of Hong Kong. Her research work focuses on the development and application of molecular and cellular contamination biomarkers, in vitro cell cultures and toxicity mechanisms, transcriptomics and proteomics, cell pathology and histopathology, in relation to chemical contamination by aromatic hydrocarbons and petroleum, endocrine disruptors, nanomaterials and microplastics. She has chaired the consolidated (type A) research group on ‘Cellular Biology in Environmental Toxicology’ since its creation in 2001, and is also chair of the ‘Protection of Ecosystem Health’ research unit as well as the lead researcher at the Centre for Biology and Experimental Marine Biotechnology (Plentzia Marine Station). She is professor of the Master's programmes ‘Erasmus Mundus in Marine Environment and Resources’ and ‘Environmental Contamination and Toxicology’. She coordinates the PhD programme ‘Environmental Contamination and Toxicology’, which received a Special Mention for Excellence from MEC. She has directed twelve doctoral theses, ten of which were recognised in Europe or internationally and one by an extraordinary doctoral prize, and she currently directs four doctoral theses. She is the author of two textbooks, sixteen book chapters and more than 150 scientific articles in indexed international journals, and has published one book and three special volumes.
