Postdoctoral research at the LMU: Next generation sequencing surveys of the marine deep biosphere evidence a high taxonomic diversity, but do not account for ecological functions or growth rates. Our work tackles this issue by extracting both DNA and RNA from oxic and anoxic deep abyssal clay of the Northern Atlantic Ocean. We apply quantitative PCR assays targeting taxonomic and functional genes, and Illumina sequencing of 16S rRNA genes, metagenomic and metatranscriptomic libraries.

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 minerals during 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.

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.

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 the maar 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.

Master's thesis: “Contribution to the study of cement stratigraphy using a multi-methodological approach”, was centered on carbonates diagenesis using cathodoluminescence, X-ray microfluorescence, fluorescence microscopy, fluid inclusions and image analysis. This Master was awarded the 2008 ELSTE Price.
