Geobiologist and Microbial Geochemist
Researcher ID: 0000-0001-5039-0543
Originally trained as a geologist, my research with SoWa-RI focuses on biogeochemical processes leading to mineral authigenesis and early diagenetic alteration in water columns and modern sediments and how does these processes can be extrapolated to understand chemical and isotopic signatures exceptionally preserved in ancient rocks. I integrate results from high-resolution (chemo)petrography; aqueous, whole-rock/sediment geochemistry (isotopic, minor and trace metals, biomarkers) and in situ spectroscopy into diagenetic interpretations. I also have expertise in mineral equilibrium and surface complexation modelling for studying the link between metal reactive organic matrices and minerals.
