Research interests

  • Using redox-sensitive metal isotopes (Mo and U) to trace the evolution of the early ocean-atmosphere system on Earth
  • Modern and ancient stromatolites
  • Tracing continental weathering processes using non-traditional stable metal isotope geochemistry (Li, Si)
  • Understanding the depletion of uranium-234 in minerals to quantify the time elapsed since the onset of comminution, i.e. comminution dating technique
