The mathematical modelling group has been headed by Prof. Dr. Dieter Wolf-Gladrow since 1993. It includes Dr. Silke Thoms and Dr. Christoph Völker as senior scientists and host Dr. Judith Hauck as Helmholtz postdoc. Dr. Silke Thoms  is an expert in modelling processes on the (sub-)cellular and ecosystem level. Her models are of great help for interpreting experimental results of the phyto-change and paleo-proxies groups as well as for the EcoTrace group. She suggests and helps in designing new experiments. Dr. Christoph Völker is one of a handful of worldwide leading experts in the modelling of iron in seawater and its impact on biological production. He develops, runs, and analyses global biogeochemical general circulation models (BOGCMs).  Dr. Judith Hauck received a Helmholtz Postdoc Award in 2014. She studies the current and future impact of climate change, especially the increase in wind forcing due to the Antarctic ozone hole and global warming, on the cycling of carbon in the Southern Ocean by further development and integrating of BOGCMs and data analysis.

Prof. Dr. Dieter Wolf-Gladrow is an expert in the marine carbonate system (CO2 in seawater). His various research interests include climate engineering/geoengineering with emphasis on ocean iron fertilization and enhanced weathering. Currently, the group encompasses four postdocs (Judith Hauck, Vibe Schourup-Kristensen, Eva Alvarez and Ying Ye), three PhD students (Essowe Panassa, Anna Pagnone, Razib Vhuijan) and one master student (Benjamin Post).
