I am a marine biologist with interests spanning all aspects of plankton (virus, bacteria, algae, mixotrophs, zooplankton), from experimental physiology, ecology through to modelling.

I work on projects ranging from ocean acidification and ocean-scale production, harmful algal blooms, to commercial exploitation of algal growth and aquaculture.

A core component of my work is modelling, for which a series of interconnecting acclimative, multi-nutrient, variable stoichiometry models have been developed. The primary applications of these are in studies of trophic dynamics for biogeochemical and ecological analyses. A secondary application is in the guise of systems-biology applications to commercial production of microalgal biomass, cost-benefit analyses and optimization.

I work with colleagues both within the UK (notably PML, NOCS) and internationally (notably EU, USA and Australia).

Teaching

  • BIO227 Marine Plankton And Oceanography

    This module introduces students to the fundamental concept of plankton ecology at level 2. Students will receive 18-20 lectures and four practicals (1 wet lab, 3 IT lab, 1 boat work). The lectures will cover three key themes: oceanography pertaining to planktonic production, plankton ecophysiology, and the functioning of the planktonic foodwebs. Three reports (1 IT-based, 1 from a lab-practical, 1 from boat work) will be assessed, together with one examination consisting of 30 multiple choice questions + one essay question + one analytical question.
