Function and Responsibilities:

Project manager of the FET Project PROSPECTOMICS

Research Interests:

After a Master in carbonate sedimentology, I moved to the field of geomicrobiology and investigated microbial populations in two lacustrine systems, namely a nitrogen-limited periglacial lake (Laguna Potrok Aike) and a phosphorus-limited tropical lake (Danau Towuti).

Then, I focused on deep biosphere activities in abyssal clay from the North Atlantic using DNA/RNA Illumina sequencing.

I presently work on complementing geological and geophysical prospecting of hydrocarbons with molecular tools.

Career:

10.2017-12.2020: Postdoctoral research: Next generation sequencing surveys of the marine deep biosphere evidence a high taxonomic diversity, but do not account for ecological functions or growth rates. My work tackled this issue by extracting both DNA and RNA from oxic and anoxic deep abyssal clay of the Northern Atlantic Ocean. We applied quantitative PCR assays targeting taxonomic and functional genes, and Illumina sequencing of 16S rRNA genes, metagenomic and metatranscriptomic libraries. (LMU Munich, Orsi's Lab)

04.2015-06.2017, Eigene Stelle DFG grant(VU 94/1-1): Inspected the formation of authigenic minerals associated with microbial activity in ferruginous sediments from Lake Towuti, Indonesia. This research was part of the ICDP-funded Towuti Drilling Project. Microbial reduction processes and organic matter degradation in the sediment induce neoformation of mineralsduring early diagenesis (e.g. siderite, magnetite, vivianite). Mineral features and isotope compositions were compared to microbial assemblages (i.e. environmental DNA) and used as modern biosignatures for the Proterozoic ferruginous oceans. (GFZ Potsdam)

10.2013-03.2015, Early Postdoc.Mobility SNSF grant(P2GEP2_148621): Addressed the link between biogeochemistry and microbial populations in the sediments of Lake Towuti, Indonesia. Due to its iron-rich settings, the lake is ideal to study metal reduction processes and their influence on the sediment composition during early diagenesis. (GFZ Potsdam)

07.2008-06.2013, PhD thesis: “Characterizing the Subsurface Biosphere in Laguna Potrok Aike Sediments (Argentina) – a Case Study -" mainly focused on deep microbial populations in the sediment of themaar lake Potrok Aike, Argentinean Patagonia (ICDP-funded PASADO project). The approach included microbiological and geochemical methods such as 16S rRNA fingerprinting (DGGE, cloning, illumina), cell count, methane and fatty acid biogeochemistry and their related isotope compositions, pore water chemistry, phosphorus speciation and others. This thesis was awarded the CHGEOL Award 2013. (University of Geneva)

08.2006-04.2008, Master's thesis: “Contribution to the study of cement stratigraphy using a multi-methodological approach”, was centered on carbonates diagenesis using cathodoluminescence, X-raymicrofluorescence, fluorescence microscopy, fluid inclusions and image analysis. This Master was awarded the2008 ELSTE Price. (University of Geneva)
