"

I am a plankton ecologist, originally trained as an algal physiologist, who works primarily using simulation modelling approaches. I am especially interested in developing plankton digital twins, through which in silico experiments can be conducted to enhance mechanistic understanding and aid education and ecosystem management.

"

My work ranges from commercial-facing microalgal production to ocean acidification impacts, harmful algal blooms, microbial and biological carbon pumps, and especially over the last decade on the mixoplankton paradigm which sees an overturning of the conventional dichotomy of phytoplankton vs zooplankton.

My interests include viruses, bacteria, cyanobacteria, phytoplankton, mixoplankton, protist and metazoan zooplankton, stoichiometric ecology, allometry, toxins, allelopaths – anything to which simulation modelling may be applied to enhance understanding.

I work at PML on integrating ecophysiology into plankton functional type models and allied cross-disciplinary activities. A new platform has been developed for describing plankton physiology and behaviour and forms the basis for plankton digital twin developments. This combines system dynamics and systems biology concepts, offering scope to merge ‘omics and traditional rate measurements with simulation modelling.

I have a particular interest in developing teaching aids for young children through to aspiring modellers.
