Can you say a few words about yourself?

I was born in Brazil and did my bachelor’s degree there. I have later moved to Germany, where I did my master’s and PhD. I am a civil and environmental engineer by training and specialize in hydrogeology and hydrochemistry. My previous research was focused on hydrochemical processes occurring during surface and groundwater interaction, with an emphasis on redox reactions and nitrogen processes in the aquifer and in hyporheic zone.

What is your role in ReCLEAN?

I am a postdoc working in the water compartment of ReCLEAN. In this work package, our primary goal is to develop predictive maps for nitrate concentrations in groundwater in Switzerland using machine learning algorithms. I aim to identify hotspots for high nitrate concentrations and to examine the combination of environmental and anthropogenic factors that lead to vulnerable areas for nitrate contamination, thus providing a tool for informed decision-making regarding mitigation and adaptation measures.

Why were you interested in ReCLEAN?

As a researcher, one wants ideally to investigate relevant subjects and have the best tools to do it. Groundwater nitrate contamination is a worldwide problem with many interdisciplinary facets. ReCLEAN gives a rare opportunity to tackle this matter as part of a joint initiative with experts from several fields, which allows us to offer an unique perspective on the matter and help improve the situation in world’s aquifers.

Can you speak about other projects you are currently working on and other ones in the past?

My previous research was focused on geochemical investigation and the application of managed aquifer recharge solutions in Vietnam, Germany and the Middle East. My contaminants of interest were ammonium, nitrate and arsenic. Currently I work in the Contaminant Hydrology department of EAWAG. Our latest research in the department is focused on the geospatial modelling of geogenic and anthopogenic contaminants at local to global scales, in both soils and groundwater.
