معرفی
Frerk Pöppelmeier serves as an Assistant Professor at the University of Bern's Climate and Environmental Physics (CEP) department, leading the Global Biogeochemical Modelling research group. His work focuses on quantifying carbon cycle dynamics and climate feedbacks through paleoclimate-informed Earth system modeling, addressing critical uncertainties in future climate projections under anthropogenic forcing.
Research centers on the Bern3D Earth system model of intermediate complexity, uniquely enhanced with diagnostic and prognostic isotope tracers (including carbon, beryllium, neodymium, protactinium/thorium, chromium species, and noble gases). This enables direct model-data comparisons with paleoclimate archives from ice cores and ocean sediments, yielding novel constraints on past ocean circulation and temperature. Current methodological development emphasizes modularizing Bern3D for flexible coupling and expanding tracer capabilities to investigate centennial-to-millennial scale climate impacts.
Active Projects
- ClimTip: Quantifying climate tipping points and systemic impacts
- Past-To-Future: Integrating paleoclimate insights into future projections
- pleistoCEP2: Pleistocene Earth system evolution analysis
Academic Leadership
Dr. Pöppelmeier mentors two PhD students (Audrey de Huu, Pierre Testorf) and collaborates with multiple postdoctoral researchers (Drs. Hofmann Elizondo, Millet, Wirths) within his group. His research directly informs policy-relevant climate scenarios through the Wyss Academy for Nature partnership, focusing on sustainable development pathways under changing biogeochemical cycles.
