Christian Deusner

Christian Deusner is a Scientist in the Research Division of Marine Biogeochemistry at GEOMAR Helmholtz Center for Ocean Research Kiel, affiliated with the Research Unit Marine Geosystems. He has been active in this role since 2009, following postdoctoral work at the Max Planck Institute for Marine Microbiology and a PhD at the UFZ Centre for Environmental Research.

• PhD, Environmental Microbiology, UFZ Centre for Environmental Research Leipzig-Halle (1999–2003)
• Postdoc, Biogeochemistry and Microbiology, Max Planck Institute for Marine Microbiology (2004–2010)
• Scientist, Marine Biogeochemistry, GEOMAR (2009–present)

His research centers on the experimental and numerical simulation of biogeochemical and geomechanical processes in marine sediments, especially under high-pressure conditions. Key interests include gas hydrate systems, thermo-hydro-chemo-mechanical (THCM) couplings, microbial metabolism under anoxia, and diagenetic processes. His work integrates laboratory experiments with field data and modeling to understand sediment behavior relevant to energy resources and carbon storage.

His recent publications (2019–2025) reflect a strong focus on gas hydrate dynamics, particularly CH4-CO2 exchange for methane recovery and CO2 sequestration, mechanical properties of hydrate-bearing sediments, and monitoring techniques for carbon storage sites. The studies employ experimental setups, numerical modeling, and field data from regions like the Black Sea and Baltic Sea, demonstrating interdisciplinary approaches across geochemistry, geomechanics, and environmental engineering.

Christian Deusner has contributed to numerous scientific projects and collaborative initiatives, including SUGAR and STEMM-CCS, and has presented at major international conferences. He co-holds a patent on deep-sea sediment stabilization and has developed advanced high-pressure experimental systems for hydrate research.

He has supervised or collaborated on multiple research efforts, particularly through joint publications and project reports, though no formal advisees are listed. His work has significant implications for offshore carbon storage, methane hydrate exploitation, and understanding marine biogeochemical cycles.
