Bernhard Ahrens

Dr. Bernhard Ahrens is a Project Group Leader at the Department Biogeochemical Integration (BGI) of the Max Planck Institute for Biogeochemistry. His research focuses on soil organic carbon (SOC) dynamics, microbial interactions, and climate change impacts through hybrid modeling approaches combining process-based models (e.g., COMISSION, Jena Soil Model) and machine learning.

• Education: Implied PhD in Biogeochemistry or related field

Research Interests revolve around:

• Soil carbon cycling and stabilization mechanisms
• Microbial carbon use efficiency (CUE) and its role in global carbon storage
• Feedback between SOC dynamics and soil structure
• Nitrogen demand effects on N2O emissions and soil aeration
• Climate-soil-moisture interactions under warming

Recent Publications highlight trends in process-based modeling, microbial stoichiometry, and climate-soil feedbacks. His work emphasizes phosphorus exchange, hydrometeorology, and radiocarbon constraints to refine carbon turnover estimates.

Scientific Awards: Not mentioned in available texts.

• Current projects: AI4SoilHealth (EU Horizon Europe, 2023–2027), co-designed with Melanie Weynants

Collaborators include doctoral researchers Mohammed Ayoub Chettouh, Leo Roßdeutscher, and former member Marleen Pallandt. The group engages in interdisciplinary research at the intersection of soil science, climate modeling, and biogeochemical feedbacks.
