Fields of study

  • Paleoenvironmental reconstructions
  • Heavy stable isotope geochemistry

Research

My current research interests focus on the geochemical interactions between atmospheric, terrestrial surface and marine processes and their influence on the evolution and development of life on our planet throughout Earth’s history. Current projects include:

  • The development of oxygenic continental weathering in the Neoproterozoic
  • Investigation of microbial activity during the formation of the massive Løkken jasper deposit in Norway
  • Transition metal cycling in cold off-spreading axis hydrothermal systems and associated microbial iron oxy-hydroxide deposits of the N-Atlantik
  • The reaction kinetics of chromium species in aqueous media and chromium isotope cycling in the oceans
  • The development of new isotope geochemical tools

I use a variety of geochemical tools and isotope systems for my research. Major tools include:

  • Major and trace element systematics
  • Radiogenic isotopes (Sr, Nd, Pb)
  • Traditional (C, O, S) and non-traditional stable (Li, Cr, Fe, Cu, Zn, Mo) isotope systems
