Marianne Nuzzo

Marianne has received her PhD. in organic geochemistry from the University of Bristol (UK), with her research bearing on the stable isotope and molecular geochemistry of methane seeps and on microbial methanogenesis. She studied Geology at the University of Toulouse (France) for her diploma, and at the University of Avignon (France) for her Master degree in Hydrogeology and Environment.

Prior to joining IGI in 2014, she worked as a post-doctoral researcher at the Marine Geology Department of the Portuguese Geological Survey; and at Geomar, the German Institute for Marine Geoscience (Kiel, Germany). Her research on the biogeochemistry of hydrocarbon fluids at marine seeps entailed investigation of the stable isotope geochemistry of hydrocarbon gases; of the biomarker geochemistry of seep oil; and of greenhouse gas fluxes in seeps from the Gulf of Cadiz (NE Atlantic Ocean), West Nile Delta (Mediterranean Sea) and offshore Costa Rica (Pacific Ocean).

Marianne is a Senior Organic Geochemist at IGI, specializing in biomarker and stable isotope geochemistry of hydrocarbon fluids.

She is also leading IGI’s Research projects to develop state-of-the art expertise in several Net-Zero and environmental geochemistry domains. In geochemistry and modelling for the Net-Zero energy transition, our focus is on (1) geological storage of CO2 (modelling CO2 migration and monitoring emissions), and (2) modelling natural hydrogen systems. In environmental geochemistry, we specialise in spill oil forensic geochemistry.

Marianne’s scientific contribution to the budding Net-Zero & environment geochemical expertise in IGI is related to monitoring of greenhouse gas emissions and to spill oil forensic geochemistry.

In her spare time, Marianne practises yoga and enjoys trekking and literature.
