My research ranges from microbial physiology to Earth system science on timescales from hours to decades. To allow this wide range of relevant processes to be integrated, I am building a global ocean biogeochemical model that is based on plankton functional types (a Dynamic Green Ocean Model). To keep this model realistic and allow extrapolation into climate change scenarios, I place strong emphasis on data-synthesis of observations to derive model equations, estimate parameters and to evaluate the results. Moreover, I incorporate known physical mechanisms and ecological relationships as additional constraints. To make use of developments in this range of research fields, I instigate and participate in many UK and international collaborations.

Integrating physiological observations of marine (micro-)organisms into descriptions of Plankton Functional Types (PFTs); modelling the role of PFTs in global ocean biogeochemical cycles (PlankTOM models).

1) Laboratory based physiology of autotrophic and heterotrophic marine microorganisms and copepods.

2) Ecological footprinting as a measure of sustainability.
