Modeling cyanobacteria ecology and toxin production (and some out-of-the-box thinking about management)

(online seminar)


We develop and apply gene-level models to understand the ecology of cyanobacteria. These models generally simulate individual cells using agent-based modeling (ABM) and resolve a number of intracellular mechanisms, like gene expression, protein translation and protein function. Starting with a model of Prochlorococcus over ten years ago, we have continually revised and advanced a workflow for the development of these models. Our model development is highly-data driven. For example, our ongoing development of the Microcystis model builds on a meta-analysis of literature encompassing over 500 laboratory experiments from over 70 papers. In this seminar, I will present two case studies: (1) Anabaena – nitrogen interaction, (2) Microcystis growth and toxin production (work in progress). I will also share some thoughts and “out-of-the-box” ideas about management. To learn more about our work see these papers:
