My research interests focus on the natural and anthropogenic trace element fluxes and their fate in the geological record and environment. With observations in the field, laboratory experiments and modeling I contribute to developing new tools to constraint spatial and temporal changes of past geosystems in response to large-scale geological processes (e.g., volcanic eruptions) in key regions of the world in order to provide decision criteria for stakeholders working to mitigate impacts and hazards on society.

Current work is focused on the impact of ash deposition in the Andes and the Chacopampean Plain in the South Cone of America (collaboration with IRNASA-CSIC and the University of Las Palmas de Gran Canaria in Spain, and the Universities of San Luis, Tucumán, Mar del Plata and Buenos Aires in Argentina). I am studying the mineral-water interaction to understand mainly the behavior of trace elements in drinking water treatment plants to improve the involved processes, including desalination plants. Key aspects are the development and application of geochemical source tracing techniques and modeling methods for water quality management in Mediterranean basins of South Europe (rivers Llobregat, Ter, Drama,…) and South America (Sali River). I develop and apply new methods for mineral exploration and environmental geochemistry based mainly on the analysis of rocks, soils, water, vegetation, etc. by ICP-MS. Recent work has developed a simple method that allows determining accurate and precise concentrations of sulfur and halogens in a multielement analysis in water by HR-ICP-MS (collaboration with the University of San Luis, Argentina). GIS-based geomorphological reconstructions also provide essential data to model the behavior of past and future environmental changes (collaboration with the University of Las Palmas de Gran Canaria, Spain).

Cerro Blanco (Central Andes): The Largest Volcanic Eruption Of The Last 5000 Years

One of the biggest mysteries concerning the origin of many recent volcanic ash deposits in NW Argentina has been solved. New data and interpretation about a major eruption — spreading more than 100 km3 of ashes over about 500.000 km2 […]
