Jiajun Wu

Dr. Jiajun Wu is a Researcher at the University of Hamburg's Institute of Oceanography, focusing on Earth System Modeling and carbon cycle dynamics. He holds a PhD from GEOMAR Helmholtz Centre and Kiel University (2024), an M.Sc. in Biological Oceanography (2016), and a B.Sc. in Marine Biology (2013). His work bridges climate science and policy, addressing ocean-atmosphere interactions, CDR validation, and macroalgae-based carbon sequestration.

Research interests include developing Earth System Models (ESMs) to assess carbon sequestration methods, evaluating ocean-atmosphere feedbacks on climate, and advancing measurement frameworks for CDR. Recent projects include the ICON-4C4M-O initiative at Hamburg and Sea4Society at the Alfred Wegener Institute.

Publications highlight contributions to CDR potential analysis, climate intervention strategies, and ocean biogeochemical modeling. Collaborative work spans interdisciplinary teams in Germany and globally, focusing on actionable climate solutions.
