About me

I am an environmental engineer, deeply interested in hydrological modeling. My work aims to improving our understanding of the links between water transit times and water quality in catchments.

Research interests

  • water age and transit times
  • solute transport in catchments
  • streamwater sampling
  • Chamberonne watershed

Education

2020 – 2023, MSc, Environmental Sciences and Engineering, specialization in water, soil and ecosystems engineering, EPFL, Switzerland

2017 – 2020, BSc, Environmental Sciences and Engineering, EPFL, Switzerland
