ETIS profile

About

I am a Research Fellow in Earth sciences at the University of Tartu in Estonia. I am fascinated by changes in nutrient cycling and rock weathering that took place on the ancient Earth, drastically affecting its oceans, atmosphere, and biosphere. To study these shifts, I utilize a variety of trace metal-based paleoenvironmental proxies preserved in ancient sedimentary rocks, especially those formed in the Palaeoproterozoic and Palaeozoic eras.

Research interests

Trace metal and nutrient geochemistry
The weathering of trace metals and nutrients on land, their transport into the marine realm, and partitioning in sediments.
Redox through Earth history
Redox evolution of the ocean and atmosphere in the Archean, Proterozoic, and Paleozoic, as well as its effects on the biosphere and global elemental cycles.
Phosphogenesis
The generation of phosphate-rich minerals and sediments. The preservation of microbes in apatite and their role in its nucleation and growth.
Weathering environments
Weathering environments as sources of nutrients to the biosphere and archives of Earth’s atmospheric composition.
Amber geochemistry
The provenance of amber deposits as revealed through their stable isotope composition and spectral characteristics.
