My most recent research has focused on the environmental distribution and impact of plastic waste, microplastics, and nanoplastics, particularly their degradation and potential ecological risks in aquatic environments. I have also worked on water treatment, especially in the development of technologies for the purification and reuse of wastewater through advanced oxidation processes, including photocatalysis, as a means to degrade persistent and emerging contaminants.
My work also investigates the distribution of anthropogenic pollutants by analyzing their sources, transformation, and distribution, as well as their effects on ecosystems. Specifically, I study the environmental toxicity of anthropogenic pollutants and their mixtures, including nanomaterials and nanoplastics, assessing their transformation and effects on living organisms.
FundingThe generation, environmental fate and and biological effects of incidental microplastics and nanoplastics
The fate and removal of aqueous (micro)pollutants from water and wastewater, especially when using advanced oxidation processes
Toxicity and ecotoxicity of pollutants and mixtures, including platic particles and nanomaterials
The production of nanostructured surfaces for water treatment processes, including electrospun nanofibrous materials, filtration membranes, and antimicrobial surfaces

The European Union (EU27 + Norway, Switzerland and United Kingdom) produces over 40 million tonnes of fossil-based polymers each year for making plastic products. Of this amount, between 11 and 13 million tonnes are lost. That is, this is plastic that is not accounted for as waste, has not been exported, and cannot be assumed to be part of durable consumer goods that have not yet reached the end of their useful life. (...)
In the EU+3, over 30 million tonnes of plastic waste are collected annually. More than 70% ends up in incinerators or landfills, while only 6–7 Mt return to the production cycle. Even more concerning is the gap of over 20 million tonnes between production and recorded waste. While part of this is stored in durable goods, such as buildings or vehicles, roughly 11–13 Mt per year can only be explained as plastic that has escaped into the environment. (...)
Water is an essential nutrient that plays vital roles in our body. Unlike other nutrients, we can barely store it, so we are forced to continually replenish it through liquid consumption. Developed societies have managed to supply the population with quality water although the occasional presence of contaminants quickly jump out to the media and generates public concern. (...)
