DOCTORAL CANDIDATE, GEOCHEMISTRY, DEPARTMENT OF EARTH SCIENCES, ETH ZÜRICH

2014 - present

Thesis research with Derek Vance entitled:

Quantifying and understanding the particulate riverine input of metals and their isotopes to the Oceans



  • Organise and execute trace-metal clean field sampling campaigns to the Kalix and Amazon Rivers

  • Development of on-board, sample enrichment procedures via cross-flow filtration to ensure enough analyte would be present in the particulate, colloidal, traditionally dissolved, and ultra-filtered size fractions for isotopic analysis of transition metals (Fe, Zn, Cu, Mo, Ni)

  • Investigate partitioning of these metals and their isotopes between the above mentioned phases

  • Development of analytical procedures for selective chemical extraction of these metals and their isotopes from the particulate phase

  • Development of new column separation techniques for Mo and Ni

  • Development of analytical techniques for analysing seawater-river water mixtures for the transition metals and their isotopes

  • Investigate (re)mobilisation of these metals and their isotopes in estuarine environments
