Brief Bio

Marine Scientist, PhD by the University of Barcelona (Spain), Master of Advanced Studies in Ecology and MSc in Sustainable Management of Coastal and Marine Systems. Full member at the management committee of the COST Action TD1407, ‘Network on Technology-Critical Elements – from Environmental Processes to Human Health Threat’s (2015 - 2019) funded by European Framework Programme Horizon 2020.

Research Interests

My research focuses broadly on the biogeochemical processes taking place in coastal and marine systems, which involves oceanographic characterization of water masses, quantification of fluxes of particulate and dissolved material in estuarine ecosystems, and sediment-water exchange in intertidal areas driven by molecular diffusion and advective transport.  

I am particularly interested in trace elements and emerging pollutants, analytical methods for its analysis and trace-clean sampling/handling methodologies. 

During the last years, I have been also working on Thallium geochemistry, focussed on three main aspects: a) the mobility of thallium in sediments, bspeciation analysis of TlI and TlII and canalytical methods for determination low concentrations of TlII.
