Research Interests

• Deep biosphere biogeochemistry
• Carbon cycling and stable isotope probing
• Transformation of organic matter during diagenesis

PhD project

My dissertation project is part of the MARUM project B2 entitled ‘Simulation of Biogeochemical Processes in the Marine Subsurface’. I will conduct microcosm experiments using a wide arrays of sediments collected from different geological settings. The scientific questions to be addressed can be divided into two parts:

• the metabolic capabilities of the novel prokaryotes discovered in the marine deep biosphere
• microbially mediated modification of organic compounds under anoxic conditions

To address these questions I will apply the following approaches:

• stable isotope labeling techniques and IRMS coupled to different interfaces
• GC-FID & RCP (H2 analyzer) for monitoring gas metabolites
• HPLC for monitoring (semi-)volatile comppounds
• molecular and genetic fingerprinting techniques for characterizing microbial community
