Research Interests

I am interested in understanding the sulfur and carbon cycles in the Archean. My research is focused on sulfur and carbon isotopic signatures in Neoarchean carbonates from Brazil, Western Australia and South Africa. Because most of the sulfur isotope measurements have been done on black shales, carbonates for a long time were not in the scope of Precambrian sulfur studies. I would like to cover this gap to see the full picture of sulfur recycling and reconcile sources of sulfur based on stable isotope geochemistry of sedimentary rocks.

In addition, I am interested in evolution of Early Precambrian atmosphere and oceans, biogeochemistry, and modern carbonate formation.
